Headphones are the standout category this Memorial Day weekend — Sony and Bose have each pushed their flagship ANC (active noise cancellation) cans below $250, both priced by Amazon directly, both with 19,000+ reviews above 4.2 stars. Kitchen and outdoor cooking are also running deep: a community-verified promo code on a smart meat thermometer blows past every tracked historical price low, and Traeger's Pro 34 pellet smoker is at a $499 Memorial Day Limited Time price that's within 5% of its all-time floor. Cashback portals (Rakuten and TopCashback) do not currently offer Amazon general-merchandise returns — both are confirmed at 0% for these product categories 1 2 — so the math below stops at the Amazon checkout price.

Five items qualified for this window. One near-miss (Chefman Air Fryer at $57.97) is excluded: it's $8 above its 90-day low of $49.97 set in December 2025. 3 Wait for it to revisit that floor.

CamelCamelCamel shows the all-time low at $243.00 (March 31, 2026) — today's $248 is within $5 of that floor. 4 Amazon sells and ships the unit directly. The product has 19,498 ratings at 4.2 stars. 5

PCMag's Tim Gideon rated the XM5 "Outstanding," writing: "Compared with the $329 Bose QuietComfort 45 and the $549 Apple AirPods Max, the 1000XM5 over-ear headphones offer comparable noise cancellation and arguably the best sound quality of the bunch." 6 That review was written at a higher price point; at $248 the gap versus the AirPods Max widens by another $150.

Should you buy? If you've been watching XM5s, this is the second time ever they've touched this price floor — the last visit was a single day in late March. Sony is a 79-year-old consumer electronics company; this is not a brand-quality gamble. Buy.

Honest alternative: The Bose QuietComfort (Item 5 in this list) at $229 — slightly lower price, higher star rating, but well above its Black Friday low. Or step up to the Sony WH-1000XM6 at $398 for the current generation.

The promo code was posted to Slickdeals (Deal Score +80, 35 comments) on May 18 and confirmed still active as of May 22. 7 CamelCamelCamel's all-time Amazon low before this code was $47.63 (December 1, 2025); the third-party new low was $37.99 (August 2025). 8 At $25.99, the promo code price beats every tracked history record. The product has 2,272 ratings at 4.5 stars, holds Amazon's Choice badge, and ranks #4 in Meat Thermometers & Timers. 9 Over 8,000 units sold in the past month.

ThermoMaven is a NIST-certified (National Institute of Standards and Technology — the US federal measurement accuracy standard) smart kitchen gadget brand with an 18-month warranty. An Amazon verified buyer who identified as a chef wrote: "Best wireless thermometer I have used, and as a chef, I have used many! Great range, great battery life for long overnight cooks." 9 The Slickdeals poster noted the $25.99 price is $4 lower than previous popular deal appearances for this product. 7

Should you buy? Yes, without much deliberation. A community-verified promo code beating the previous all-time Amazon low by 45%, on a 4.5-star brand-name thermometer with an accuracy certification, is exactly the kind of stack this radar exists to surface. Enter code BIPGAQM7 at checkout; verify the $25.99 price before completing the order.

Honest alternative: The Meater Plus at $79 for Bluetooth + cloud connectivity if you want app-based ambient temperature monitoring. At four times the price, it solves a different problem.

CamelCamelCamel shows the all-time low at $259.00 set on April 21, 2026 — today's price ties that floor exactly. 10 AllRecipes editorial and Forbes Vetted both featured it as a top Memorial Day kitchen appliance pick. 11

One transparency note: Amazon's product page was blocked by anti-bot protection during research. Review count, star rating, and clip-coupon status could not be directly verified. 10 The brand — SharkNinja, the parent company behind both the Shark and Ninja appliance lines, established 1994 — typically carries thousands of reviews across its product line at 4.3+ stars, but those numbers are inferred from brand-level data, not confirmed on this specific ASIN. Verify the star rating and review count on the product listing before buying.

The SLUSHi (model FS301) makes frozen margaritas, slushies, and blended drinks with a self-contained freezing system — no ice required. It's a niche appliance for a specific use case.

Should you buy? If you host regularly in summer and were already eyeing the SLUSHi, tying its all-time low is a legitimate signal. If this is an impulse buy because it showed up in a deal roundup: it's a $260 blender-adjacent appliance with one primary use. Would you buy it at $350? That's the real question.

Honest alternative: The Nostalgia Electric Snow Cone Maker at approximately $35 — $224 cheaper, limited to crushed ice rather than frozen cocktails, but fine for a casual backyard setup.

CamelCamelCamel puts the all-time Amazon low at $474.99 on June 26, 2024. 12 Today's $499 is $24 above that floor — close, but not a new low. The product has 2,336 ratings at 4.5 stars and ranks #2 in Combination Grill-Smokers. 13 Over 600 units sold in the past week, with free shipping on Amazon.

Traeger is the original wood pellet grill inventor (established 1985) — this is the Pro 34, their mid-range model with 884 square inches of cooking area across two grates. One Amazon reviewer wrote: "I was skeptical at first that I made the right choice however, after using it several times I have fallen in love." 13 Recurring complaints in customer reviews mention temperature control inconsistency and shipping damage — worth reading the 1-star reviews before ordering.

A few caveats: multiple Amazon reviewers and the Slickdeals community signal is weak (no vote-verified deal thread found). Men's Journal described the $499 price as a "rare 32% off," but the all-time low at $474.99 complicates that framing — this is not a price history debut.

Should you buy? If you've already decided on a pellet smoker and Traeger specifically, $499 is a reasonable price with historical support. If you're comparing pellet smoker options broadly, check whether the ATL at $474.99 returns this summer before buying.

Honest alternative: The Camp Chef Woodwind Pro 24 is consistently rated alongside Traeger with reportedly stronger temperature accuracy — compare current pricing before committing.

The all-time Amazon low is $159.99, set on November 30, 2025 — almost certainly Black Friday. 14 The 90-day low data was not available in the research data. Today's $229 represents a 34% discount from MSRP, but it's $69 above the Black Friday floor. Amazon sells and ships directly. The product has 19,825 ratings at 4.6 stars. 15

PCMag featured the QuietComfort at $229 alongside the Sony XM5 in its Memorial Day tech roundup. 6 At 4.6 stars on nearly 20,000 reviews, the QuietComfort has a stronger average rating than the XM5 — but the XM5 is closer to its own historical floor in absolute dollar terms. One Amazon buyer wrote: "If you're looking for your first pair, then I would definitely recommend the QuietComfort over all the others I mentioned, even at $349." 15

Should you buy? If headphones are your target and you're indifferent between Sony and Bose: buy the Sony XM5 at $248 instead — it's closer to its all-time floor, you get three-mic ANC and LDAC high-res Bluetooth, and the price difference is only $19. The Bose earns its place here because it's a legitimately excellent headphone at a real discount, but the Black Friday floor at $160 is a meaningful data point to hold in mind.

Honest alternative: The Sony WH-1000XM5 at $248 (Item 1 in this list) — $19 more, closer to its all-time low, PCMag "Outstanding" rating.

For both high-confidence picks, the price math is independently verifiable right now:

For the three coin-flip items: run the ASIN through CamelCamelCamel or Keepa to see the 90-day price chart before deciding. If the current price is not near a floor, the Memorial Day label is doing more work than the discount itself.
