October 18 Amazon board: five 90-day lows, and a 35% coupon under three of them
Five Amazon listings at their three-month lows, three of them sitting under one 35% Blue Buffalo Subscribe & Save coupon, plus nine offers docketed for failing a single gate.
Coverage window and category weather
This board covers October 11 through October 18, 2026, through 08:00 Pacific. Every price was read off a live Amazon listing this morning and checked against that listing's three-month record.
Pet food, pantry snacks and sun care produced this week's only stacked floors. Electronics produced bare cuts: a Fire HD 10 at $72.99 against a $154.99 list, and Panasonic eneloop AAAs at $30.16 against $45.99, neither carrying a coupon or Subscribe & Save 12. Amazon's public Lightning Deals inventory still cannot be read as a list, so this weather covers only what was readable.
What cleared both gates
Five listings cleared both filters: a three-month-low shelf price, and a stackable layer. One mechanism produced three of them — a 35% Blue Buffalo coupon that appears with Subscribe & Save, on the first order only.
Cashback adds nothing this week: TopCashback's Amazon page still covers devices only, so every chain below stops at zero 3.
| Item | Shelf → landed | Net off reference | Verdict |
|---|---|---|---|
| Hawaiian Tropic Sheer Touch SPF 30, 12 × 2 oz (B0FR574WTL) | $11.08 → $10.53 | 65% | High-confidence |
| Lorna Doone Shortbread, 36 snack packs (B01LYDBRYF) | $16.19 → $13.84 | 53% | High-confidence |
| Blue Buffalo Life Protection Chicken Adult, 15 lb (B0009YUGAG) | $39.97 → $24.68 | 45% | High-confidence |
| Blue Buffalo Health Bars, Pumpkin & Cinnamon, 16 oz (B003P9XG68) | $4.98 → $3.08 | 56% | High-confidence |
| Blue Buffalo Life Protection Chicken Puppy, 15 lb (B0009YWKU0) | $39.58 → $23.15 | 53% | Coin-flip |
The five, and what each one is worth
Hawaiian Tropic Sheer Touch Lotion, SPF 30, 12 × 2 fl oz
ASIN B0FR574WTL — 4.7 stars across 12,819 ratings.
The math: $29.91 typical price → $11.08 shelf → 5% Subscribe & Save → $10.53, or 88 cents a bottle. That is 65% off the reference price 4.
The tracker's line held at $41.88 into August, stepped to $30 at month's end, then fell to $11.08 in early October and stayed 5. That is the lowest price on the listing's record. The Slickdeals thread, posted October 17, is at 32 votes, the strongest crowd signal here 6.
Should you buy? High confidence. The shelf price is 74% below what the listing charged all summer, on a product with 12,819 ratings. The catch is format: 2-ounce bottles suit a bag or a car, and a bathroom bottle is a different purchase.
Lorna Doone Shortbread Cookies, 36 snack packs
ASIN B01LYDBRYF — 4.7 stars across 1,698 ratings.
The math: $29.49 typical price → $16.19 shelf → a 10% coupon that unlocks with Subscribe & Save → the 5% Subscribe & Save rate → $13.84, or 38 cents a pack. That is 53% off the reference price 7.
The tracker shows this listing between $30 and $36.74 through August and September, then down to $16.19 this week, its three-month low 8. The thread is at 2 votes, the thinnest signal here 9.
Should you buy? High confidence. The price came down off $30 in one week, with a coupon underneath it. The format decides it: 36 packs are lunchbox stock, and cookies for a plate at home pay for the wrapping.
Blue Buffalo Life Protection Chicken Adult Dry Food, 15 lb
ASIN B0009YUGAG — 4.7 stars across 29,794 ratings.
The math: $44.49 list → $39.97 shelf → the 35% Subscribe & Save coupon → the 5% Subscribe & Save rate → $24.68, or $1.65 a pound. That is 45% off list 10.
The tracker tells a different story. The line has sat flat at $39.97 for three months, so the shelf price is its low and has not moved; the discount is all coupon 11. The Slickdeals thread is at 12 votes 12.
Should you buy? High confidence, if this food is already in your house. $24.68 for a 15-pound bag is close to half list. The 35% covers only the first delivery; the standing order after it carries the 5% rate alone.
Blue Buffalo Health Bars, Pumpkin & Cinnamon, 16 oz
ASIN B003P9XG68 — 4.7 stars across 10,128 ratings.
The math: $6.99 list → $4.98 shelf → the 35% coupon → the 5% Subscribe & Save rate → $3.08. That is 56% off list 13.
The tracker's line is flat at $4.98 for three months, the same shape as the adult food 14. Its all-time low is $2.91, set in 2018. The thread is at 21 votes, second-highest here 15.
Should you buy? High confidence. Three dollars is the smallest commitment here, and the low-risk way to test whether the coupon appears on your account. The Wild Bits in the same line sit in the docket below.
Blue Buffalo Life Protection Chicken Puppy Food, 15 lb
ASIN B0009YWKU0 — 4.7 stars across 15,262 ratings.
The math: $48.99 list → $39.58 shelf → the 35% coupon → the 10% Subscribe & Save rate → $23.15, or $1.54 a pound. That is 53% off list 16.
The three-month line is flat at $39.58, so the shelf price is the floor and nothing more 17. Its lowest recorded price is $20.89, from 2016. The thread is at 9 votes 18.
Should you buy? Coin-flip. The math is as clean as the adult bag's. A 15-pound bag is a month of puppy food, the price has not moved in three months, and this week offers only the coupon. Buy it if a puppy is eating it now; otherwise take the adult bag.
Near misses worth naming
Lysol All Purpose Cleaner Spray, 2 × 32 oz (B0BNP5QQ53) drew 173 votes, the most of any Amazon thread this week. The live listing reads $7.63 with no clip coupon, so the thread's $4.73 no longer reproduces; only the 5% rate is left. 19 Skip.
Garnier Micellar Water, 13.5 oz (B017PCGABI) carries the week's best beauty coupon, $2.83 off, landing $5.55 with Subscribe & Save on 75,592 ratings. The shelf price fails: $8.82 is the top of its three-month band, whose low is $8.39. 20 Skip.
Blue Buffalo Wilderness Wild Bits, 4 oz (B00KRMMJV4) has the same 35% coupon and 4,652 ratings, but $4.98 is its three-month high; the low is $3.73. 21 Skip.
OdoBan Disinfectant Spray, 3 × 32 oz (B079Z6XH36) is $10.14 against a $27.24 list, 63% off on 8,565 ratings, with no coupon or Subscribe & Save to stack. 22 Skip — one layer short.
Charms Mini Pops, 400 count (B077V9DS6B) sits at a $13.14 three-month low with a 15% coupon and the 5% rate, but its list price is that same $13.14, so the stack nets 19%. 23 Skip. The method Daily Shower Cleaner four-pack (B09DQ98BSC) is the same shape at 14%. 24 Skip.
Three failed the review gate. Community Coffee Signature Blend (B07X1495W9) is at a $35.29 low on 567 ratings 25. Finish Free & Clear pods (B0H7DY3MPY) has a 30% coupon at $22.99 on 77 ratings 26. Chefman's indoor pizza oven (B0CM2YBHZ3) is $199.98 against a $499.99 list on 553 ratings 27. Skip all three.
What would change the verdict
A pick leaves the board when either layer goes: the coupon disappears, or the shelf price climbs off its three-month line. For the Blue Buffalo listings the coupon is the entire discount, so a listing that loses it is plain retail.
Two checks are yours before checkout. Confirm the coupon appears on your account page, since these offers are often limited to selected accounts. Then compare the chart's right edge with the price in your cart.
