September 7–13 Warehouse Club Scorecard: Costco's Fresh Book, Sam's Small Math, BJ's Gas Benchmark
Costco is the best single stop for the new September 8 offers, Sam's wins the five-pound nugget comparison and several household near-ties, and BJ's remains a fuel benchmark when the local pump confirms it.
For September 7–13, 2026, Sam’s Club still wins the cleanest frozen-food comparison, while Costco’s new weekly page adds fresh food and beauty offers that make Costco the better single-stop run. BJ’s remains useful as a fuel benchmark. Its public product-coupon pages still do not expose enough current price-and-expiration pairs for a merchandise win. An auditable in-warehouse photo confirmation for the rows below was unavailable, so the scorecard uses readable official pages and current deal pages and leaves photo-only claims out.
Headline picks
- Sam’s Club wins the five-pound nugget comparison. Tyson chicken nuggets are $9.97 after $2 off at Sam’s. Costco’s Yummy Dino Buddies are $10.99 after $4 off. Both bags weigh five pounds, so Sam’s is $1.02 cheaper at checkout and about 21 cents cheaper per pound. The brands differ, so the result is a size-and-category win rather than a taste verdict. Five pounds is a freezer commitment. A one- or two-person household should buy this bag only when several meals are already planned. 12
- Sam’s Club edges Costco on Gain + Oxi by one cent. Both clubs list the same 170-ounce jug rated for 159 loads. Sam’s lists $15.98 after $4 off; Costco lists $15.99 after $4 off. Both prices land at about 10 cents per load. A one-cent lead cannot pay for an extra drive. Buy the detergent at the club already on your route. The current book runs through September 20. 12
- Sam’s Club takes Dawn Powerwash by one cent. Sam’s lists the matching starter-plus-refills format at $9.98 after $3 off. Costco lists its three-piece set at $9.99 after $3 off. The set contains one starter bottle and two refills. The practical winner is the club that is closer, especially for a small household that still has an unopened refill. 12
- Costco wins Mr. Clean Magic Erasers. Costco’s 18-count pack is $10.99 after $3 off. Sam’s lists the same count at $11.98 after $3 off, leaving Costco 99 cents cheaper. Eighteen erasers fit more easily into a normal utility closet than a mega-pack, but the pack still belongs on a planned cleaning list. 12
Costco’s current weekly page also adds several new-to-this-edition offers. WestEnd Cuisine grilled chicken skewers are $4.50 off for a 14-count pack from September 8–21. Kirkland ham is $2.30 off for a two-count 24-ounce pack from September 8–14. Kraft Lunchables Snackables are $10.99 after $3.50 off for six twin packs through September 20. Those offers strengthen Costco’s fresh-food stop, even when they do not create a same-product Sam’s comparison. 3
Category-by-category comparison
| Category | Costco | Sam’s Club | BJ’s | Qualified verdict |
|---|---|---|---|---|
| Food | Yummy Dino Buddies, 5 lb, $10.99 after $4 off through Sept. 20. New weekly rows include WestEnd chicken skewers, $4.50 off through Sept. 21; ham, $2.30 off Sept. 8–14; and Lunchables Snackables, $10.99 after $3.50 off through Sept. 20. 23 | Tyson chicken nuggets, 5 lb, $9.97 after $2 off through Sept. 20. Other live sale rows include Kraft Macaroni & Cheese, 18 boxes, $10.96 after $4 off; Premier Protein, 15 shakes, $19.97 after $6.67 off; and Totino’s Pizza Rolls, 160 count, $9.47 after $2 off. 1 | No current merchandise row with both a readable sale price and expiration date was verified. BJ’s public Smart Saver page was inaccessible beyond an Akamai protection screen. 4 | Sam’s wins the five-pound nugget comparison. Costco has the broader fresh-food list this week. |
| Household | Gain + Oxi, 170 oz / 159 loads, $15.99 after $4 off; Dawn three-piece set, $9.99 after $3 off; Magic Erasers, 18 ct, $10.99 after $3 off; Downy, 39.9 oz, $15.99 after $4 off. All run through Sept. 20. 2 | Gain + Oxi, same 170 oz / 159 loads, $15.98 after $4 off; Dawn set, $9.98 after $3 off; Magic Erasers, $11.98 after $3 off; Downy, $15.98 after $4 off. All run through Sept. 20. 1 | No readable current merchandise coupon row. | Costco wins the erasers; Sam’s wins the other three by one cent. The route should decide the near-ties. |
| Electronics | Shark FlexStyle IonCurl styling system, $239.99 after $60 off through Sept. 20. 3 | The public September Instant Savings page exposes the event but no item-level electronics price that can be compared. 5 | No current item-level electronics sale with a readable expiration date was verified. | No cross-chain winner. Costco has the actionable single-club offer. |
| Tires | No current Costco tire row with a complete comparable price and validity window was readable in this pass. | No comparable public Sam’s tire sale row was verified. | BJ’s tire and Smart Saver surfaces did not expose a complete current price-and-date pair. 4 | No qualified winner. Check the local tire center for installed-price terms before driving. |
| Travel | Costco Travel’s Labor Day offer says eligible packages and cruises must be booked by September 11; the public landing page gives no single package price that can be compared here. 6 | The public Instant Savings book supplies no comparable travel package price. 5 | No comparable current BJ’s travel price and deadline pair was verified. | No cross-chain winner. Costco has the only dated travel lead, and availability must be checked before booking. |
| Gas | A national Costco average was unavailable. Use the local station price before adding a detour. | Sam’s lists member-only fuel prices as a benefit, but a national Sam’s average was unavailable. Plus includes early shopping hours and 2% Sam’s Cash. 7 | BJ’s public tracker shows a U.S. regular-gas average of $3.889 per gallon on September 8. AAA’s same-day national regular average is $4.1514, putting the BJ’s benchmark 26.24 cents lower. 89 | BJ’s is the available benchmark lead, not a universal three-way winner. Local pump prices decide. |
The Sam’s book and Costco book both remain active through September 20, so the same five-pound and household comparisons are still live during this publication week. Costco’s new weekly rows create the actual change from last Tuesday: fresh deli, breakfast, beauty, and household offers now sit beside the long-running book. Sam’s Plus members also get early shopping hours, which can matter when a sale item is scarce. 127
Cherry-picker’s route
Single-stop choice: Costco. Costco is the better Tuesday run when the list includes fresh food, the Shark FlexStyle, or the cheaper Magic Erasers. The Costco weekly page has dated offers beginning September 8, while its broader book keeps the detergent and cleaning rows live through September 20. 23
Put these items on the Costco list:
- WestEnd chicken skewers, 14-count, $4.50 off, starting Sept. 8; buy only when the freezer or meal plan can use the pack. 3
- Kirkland ham, two 24-ounce packs, $2.30 off Sept. 8–14; two packs are a lot for one or two people unless one pack will be frozen. 3
- Magic Erasers, 18 count, $10.99 after $3 off, through Sept. 20. 2
- Gain + Oxi, 170 ounces / 159 loads, $15.99 after $4 off, through Sept. 20. The jug is a poor fit for a small household that does few laundry loads. 2
Add Sam’s as the second stop when the trip already passes a Sam’s location or the freezer plan calls for Tyson nuggets. Sam’s also has a useful pantry list: Kraft Macaroni & Cheese, Premier Protein, Rao’s sauce, and Totino’s Pizza Rolls. A 160-count pizza-roll bag and an 18-box macaroni pack are event quantities for a one- or two-person household, not automatic bargains. 1
Membership math
Costco lists Gold Star at $65 and Executive at $130. The $65 upgrade divided by the 2% Executive reward produces a simple break-even point of $3,250 in eligible annual spending. Costco excludes some purchases from the reward, so the relevant figure is qualified spend rather than total warehouse spending. 10
Sam’s lists Club at $60 and Plus at $120. The $60 upgrade divided by the 2% Sam’s Cash rate produces a simple break-even point of $3,000 in qualifying annual spending. Plus also includes free shipping and delivery from the club on qualifying orders, early shopping hours, pharmacy and optical savings, and tire-and-battery benefits. New members can pay $25 for Club or $55 for Plus through September 30, but the first-year promotion does not set the renewal math. 7
BJ’s current public membership page confirms that Club+ earns 2% back on most BJ’s purchases, but the accessible page does not print the current Club and Club+ annual fees. The break-even formula is the Club+ upgrade fee divided by 0.02. A $60 upgrade would equal $3,000 in eligible spending, while a different renewal difference produces a different threshold. Check the renewal screen before treating that example as your number. 11
Next week’s preview
The first short clock is Costco’s September 8–14 ham offer. Costco’s chicken skewers run through September 21, and the wider Costco and Sam’s books run through September 20. Costco Travel’s Labor Day booking deadline is September 11. Next Tuesday’s issue should begin with those deadlines, any Sam’s stock limits, and a fresh attempt at BJ’s public Smart Saver rows. 36
The weekly verdict is narrow and useful: Costco is the best single stop for the new September 8 offers; Sam’s is cheaper on the five-pound nugget comparison and several household near-ties; BJ’s is a fuel stop only when the local pump confirms the price. Costco is not always cheapest. This week’s receipts depend on the item, the pack size, and the drive.
