Amazon deal radar: Prime Day Day 2 — coupon wave hits, WONDERBOOM 4 restocks

Price Drop Lab
Price Drop Lab@NeoDrop Official

Three clip coupons appeared overnight on Day 2 — Sony WH-CH720N drops to $70.55 effective (61% off) and Apple Watch S11 falls to $223.20 effective (44% off) by stacking a 20% coupon on the $279 ATL sticker. WONDERBOOM 4 restocked at $49.39 after being OOS all of Day 1. Six BUY NOWs total; AirPods Pro 3 earns a coin-flip at $143.20 effective (sticker still $10 above the pre-Prime Day ATL). Two days remain.

Three clip coupons appeared overnight that weren't there on Day 1. WONDERBOOM 4 — which was out of stock for the entire first day — is back. Two days of Prime Day remain after today (June 25–26), so this is not the time for patience if the math already works.
Cashback note (all items): No portal stacking available. Rakuten is de-affiliated from Amazon ($0 cashback). TopCashback is limited to Amazon Devices only, rate unconfirmed. Capital One Shopping has no public Amazon rate. Effective cost = sale price minus any clip coupon you manually activate at checkout. 1

Category weather — June 24

Electronics is the deepest category for Day 2, with 50%+ discounts appearing across headphones, TVs, and wearables. 2 The Sony WH-CH720N now has a 15% clip coupon stacked on its $83 ATL price, bringing effective cost to $70.55 — the single largest percentage off any item this tracker has featured. 3 Apple Watch S11 added a 20% coupon on top of its $279 ATL sticker, making $223.20 the new effective price. 4
Home / security is equally active. Blink Mini 2 holds at $12.99 (68% off), and the WONDERBOOM 4 portable speaker is back in stock after being out all of Day 1. 5 6
Kitchen is quiet. Instant Pot Duo Plus 6QT likely holds at $69.99 but was not independently confirmed by any Day 2 publisher among 11 outlets scanned — no Day 2 cite available for that item. Treat it as carry-over, not a fresh pick.
Outdoor is weak. No outdoor items clear the editorial gates today.

Full board — June 24 (Prime Day Day 2)

1. Sony WH-CH720N — $70.55 effective 🟢 BUY NOW (new ATL + 15% coupon, 61% off)

$179.99 MSRP → $83.00 sale → clip 15% coupon at checkout → $70.55 effective | 61% off MSRP | ASIN B0BS1QCFHX | in stock 3
Day 1 had the $83.00 ATL sticker. Day 2 adds a "Save 15% at checkout" clip coupon — meaning the effective price drops to $70.55, a figure that didn't exist on this item 48 hours ago. The CCC ATL was $83.00 (set June 23); the coupon makes the real cost $12.45 lower. 3 CNET confirms the $83 base independently. 7
This is a mid-tier Sony: 35-hour battery, active noise cancellation, lightweight build. Not a flagship — but at $70.55 it is competing against earbuds and budget headphones that offer less. The coupon does not require Subscribe & Save. Clip it on the product page before adding to cart; it stays applied through checkout.
Math: $179.99 → $83.00 (sale) → −$12.45 (15% coupon) → $0 cashback → $70.55 effective | 61% off MSRP. 📈 90-day price chart
Verdict: 🟢 High-confidence. The coupon makes the math indisputable. Used units start at $75.53, making new-with-warranty at $70.55 the obvious call. 3
Alt: Sony WH-1000XM5 at $198 (50% off $400 MSRP), confirmed by multiple publishers 2 — if flagship ANC and better call quality matter, $127.45 more for 6× more powerful noise cancellation is the case.

2. Apple Watch Series 11 (42mm GPS) — $223.20 effective 🟢 BUY NOW (ATL + 20% coupon, 44% off)

$399.00 MSRP → $279.00 sale → clip 20% coupon at checkout → $223.20 effective | 44% off MSRP | ASIN B0FQFL8PZ5 | in stock 4
The sticker price ($279) has not moved from Day 1 — still the confirmed all-time low. 8 What changed overnight is a 20% clip coupon that brings the effective price to $223.20. At $279, this was already 30% off MSRP — at $223.20, it's 44% off.
The Series 12 cadence question is real: Apple typically announces the next Watch in September. At $223.20, the choice is between paying ~$177 less than a future Series 12 will likely cost at launch, in exchange for approximately 14 months without the newest hardware. The r/the5krunner community confirms watchOS support will continue for S11 into the next major software cycle. 8 Five publishers — CNN Underscored, ZDNET, CNET, WSJ BuySide, and USA Today — confirm the $279 sticker independently. 6 2
Math: $399.00 → $279.00 (ATL sale) → −$55.80 (20% coupon) → $0 cashback → $223.20 effective | 44% off MSRP. 📈 90-day price chart
Verdict: 🟢 High-confidence. At $223.20 the ceiling argument disappears. OOS risk is real given 10K+ units sold per month; the coupon may not last through Day 3–4.
Alt: Apple Watch SE 3 (~$199 on sale) — loses ECG, blood pressure monitoring, and the always-on display, but saves approximately $24 at effective price.

3. WONDERBOOM 4 — $49.39 🟢 BUY NOW (RESTOCKED, 51% off)

$99.99 MSRP → $49.39 Prime Day Deal → no coupon → $49.39 effective | 51% off MSRP | ASIN B0BRXJVG1S | in stock 5
This was the most painful item on Day 1: out of stock across all verified channels at what would have been an all-time low buy. It restocked overnight at the same $49.39 ATL price. 5 (WSJ BuySide and Wirecutter list the price at $62 — likely a different color/variant; the Amazon direct listing via ASIN B0BRXJVG1S shows $49.39.) 9 10 The regular sale price is $51.99; $49.39 is below that floor. 5
The WONDERBOOM 4 is IP67 waterproof, 14-hour battery, 360° sound, floats in water. At 51% off, it clears the editorial gate with room to spare. Two caveats: (1) restock quantities are uncertain — this item went OOS once already, and (2) at $49.39 it is $2.60 below the regular sale price, not a dramatic discount over what you'd normally see on a good day.
Math: $99.99 → $49.39 (Prime Day ATL) → no coupon → $0 cashback → $49.39 effective | 51% off MSRP.
Verdict: 🟢 BUY NOW. It was OOS once. Don't test that twice.
Alt: JBL Clip 5 (~$40–$50 on sale) for an ultra-compact carabiner-clip speaker; Bose SoundLink Flex 2 ($129 on sale) if you want louder outdoor sound at $80 more.

4. Fitbit Charge 6 (Obsidian) — $85.45 🟢 BUY NOW (down $4.50 from Day 1, 47% off)

$159.95 MSRP → $85.45 → no coupon → $85.45 effective | 47% off MSRP | ASIN B0CC62ZG1M | CCC + ZDNET confirmed 11
The price dropped $4.50 from Day 1's $89.95. CCC shows $85.45 as the new all-time low (set June 24). 11 ZDNET independently confirms $85 ("save $75, 47% off"). 2 A caveat: the Amazon product page file was corrupted during Day 2 verification, so stock status is unconfirmed from that source — CCC and ZDNET are the two independent confirmations in hand.
This is the same Charge 6 that DC Rainmaker called "arguably the best bang for your buck fitness tracker" and PCMag rated Outstanding. Built-in GPS, ECG, AMOLED display, 40+ exercise modes. The $4.50 drop is a genuine price improvement, though it closes no stackable savings gap (no coupon detected, no S&S on this item).
Math: $159.95 → $85.45 (new ATL) → no coupon → $0 cashback → $85.45 effective | 47% off MSRP.
Verdict: 🟢 High-confidence. A confirmed price drop mid-Prime Day at an already-strong ATL is the opposite of a reason to wait. Verify stock status on the product page before purchasing.
Alt: Fitbit Air (~$85 on sale, screenless, Whoop-style continuous monitoring) for readers who prefer passive tracking over a display; Garmin Vivosmart 5 (~$100–$130) for deeper athletic metrics.

5. Blink Mini 2 — $12.99 🟢 BUY NOW (68% off, holds from Day 1)

$39.99 MSRP → $12.99 Prime Day Deal → no coupon → $12.99 effective | 68% off MSRP | ASIN B0BWWZXWPL | in stock 6
Nothing has changed except the price is $0.01 lower than Day 1 ($13.00 → $12.99, rounding). This is still the cheapest indoor camera this tracker has featured. CNN Underscored and ZDNET both confirm $13. 6 2 At 68% off, the only meaningful question is whether you want an indoor camera at all.
The Blink Mini 2 is Alexa ecosystem. 1080p HD, motion detection, basic privacy features. No subscription required for motion alerts. Best for renters who don't want to drill anything.
Math: $39.99 → $12.99 → no coupon → $0 cashback → $12.99 effective | 68% off MSRP.
Verdict: 🟢 High-confidence. At $13, this is a spot-check purchase, not a deliberation.
Alt: Blink Outdoor 4 single camera ($27.99, 65% off) for outdoor use; TP-Link Tapo C210 (~$24–$30) if you want a non-Alexa ecosystem alternative.

6. Garmin Instinct 3 AMOLED — $299.99 🟢 BUY NOW (holds at ATL, 33% off)

$449.99 MSRP → $299.99 sale → no coupon → $299.99 effective | 33% off MSRP | ASIN B0DSC8JF59 | in stock 12
$299.99 has been the confirmed all-time low since May 7 — 48 days of stable floor pricing. 13 Amazon lists 2,000+ units sold in the past month. No clip coupon was detected on Day 2, and no Day 2 publisher specifically highlighted this model (ZDNET covered the Garmin Epix 4 Sapphire at $499 instead). 2 That absence doesn't change the price math, but it does mean no fresh community signal either direction.
The Instinct 3 AMOLED is Garmin's rugged outdoor watch with a power-hungry but high-contrast display: multi-band GPS, 5ATM water resistance, full sports tracking. No Apple Health sync. If you live in the Garmin ecosystem, this is a 48-day stable floor with no downward pressure in sight.
Math: $449.99 → $299.99 → no coupon → $0 cashback → $299.99 effective | 33% off MSRP.
Verdict: 🟢 High-confidence. Price has not moved in 48 days. It won't drop further during a 4-day event.
Alt: Coros Apex 2 Pro (~$350) for multi-band GPS with a titanium bezel; Garmin Instinct 2 Solar (~$200–$220 on sale) if battery life matters more than the AMOLED screen.

Coin-flip — AirPods Pro 3: $143.20 effective with 20% coupon (⚠️ complicated)

$249.00 MSRP → $179.00 sticker → clip 20% coupon at checkout → $143.20 effective | 43% off MSRP | ASIN B0FQFB8FMG | in stock 14
The sticker dropped $0.99 from Day 1 ($179.99 → $179.00). More importantly, a 20% clip coupon appeared overnight — making the effective price $143.20 if you activate it at checkout. 14
Here is the honest version of the math problem: the true all-time low for these earbuds is $169, set two weeks before Prime Day. 15 That $169 price appeared without any coupon. Prime Day's sticker ($179) is $10 above that ATL — and the r/amazonprime community has noticed: "I was able to get them for $169 two weeks ago. I guess prime deal is non existent." 16
So where does the 20% coupon leave things? At $143.20, the effective cost is $25.80 below the $169 ATL — a genuine improvement. The sticker itself is not an ATL, but the sticker-plus-coupon effective price is a new floor.
The catch: it isn't confirmed that this coupon will persist through Day 3–4. If it does, the buy decision is clear. If Amazon pulls the coupon and the sticker drops to $159 without a coupon, the comparison changes.

Math: $249.00 → $179.00 (sale) → −$35.80 (20% coupon) → $0 cashback → $143.20 effective | 43% off MSRP.
Verdict: ⚠️ Coin-flip. The coupon math is favorable. The pre-Prime Day $169 ATL without a coupon means the sticker price alone is not special. Buy today if $143.20 with a coupon is better than you expect to see again; hold if you believe the sticker will drop to $159 or below on Day 3–4 with no coupon needed.
Alt: Samsung Galaxy Buds 3 Pro (~$139–$159 on sale) for Android-first listeners; Nothing Ear (a) at $53 (46% off) 17 for budget ANC earbuds with strong community reviews.

Items not qualified today

Echo Spot 2024 (B09B96XC75) and Echo Dot Max (B0D6SZKGT4): Amazon returned errors on both verification attempts (503 / corrupted file); CCC is Cloudflare-blocked. Publisher consensus puts Echo Spot at $44.99 and Echo Dot Max was not confirmed at $54.99. Neither item will appear on the board until price is independently verified — ZDNET and CNET confirm $44.99 for the Echo Spot, which preserves its Day 1 BUY NOW status if you trust publisher confirmation alone. 2 7 The $54.99 target for Echo Dot Max has not been confirmed by any source.
Levoit LVAC-200 (B0CB6B2JWG): Sticker is $129.98 — $10 above the $119.99 target that would make this a confident buy. Not featured on any Day 2 publisher list. Still a coin-flip; check again Day 3–4. 18
Two days of Prime Day remain (June 25–26). Day 3 priorities: Echo Dot Max $54.99 target, Echo Spot verification, Levoit $119.99 watch.
