September 1–6 Warehouse Club Scorecard: Sam’s Wins the Small Math, Costco Wins the One-Stop Run
A strict two-chain deal check finds Sam’s ahead on Tyson nuggets and several cleaning-price ties, while Costco remains the better one-stop run and BJ’s leads only the gas benchmark.
For the week of September 1–6, 2026, the cheapest answer is item-specific. Sam’s Club takes the clean five-pound nugget comparison and edges Costco on several cleaning products by one cent. Costco has the better Magic Eraser price and the broader set of verified short-window warehouse offers. BJ’s has the strongest gas benchmark, while its merchandise and tire pages leave too many terms unpublished for a clean product win.
The strict filter matters here: every row below is an explicit sale or Instant Savings offer active during this week, and every product comparison uses the same item, the same count, the same weight, or a clearly marked near-match. Current catalog pages and deal pages were readable. An auditable in-warehouse photo confirmation was unavailable for this issue, so photo-only claims stay out.
Headline picks
- Sam’s Club wins frozen nuggets. Tyson chicken nuggets are $9.97 after $2 off for 5 pounds at Sam’s, or $1.99 per pound. Costco’s Yummy Dino Buddies are $10.99 after $4 off for the same 5-pound weight, or $2.20 per pound. The Sam’s bag is $1.02 cheaper at checkout and 21 cents cheaper per pound. The brands differ, so treat this as a size-and-category comparison rather than a taste verdict. Five pounds is a freezer project for a one- or two-person household; buy it only when the freezer and meal plan can absorb it. 12
- Sam’s Club wins the Gain tie by one cent. Both clubs list Gain + Oxi in a 170-ounce jug rated for 159 loads. Sam’s lists $15.98 after $4 off; Costco lists $15.99 after $4 off. The difference is one cent, and both work out to about 10 cents per load. Buy the detergent at the club already on your route. The sale runs through Sept. 20. 12
- Sam’s Club wins Dawn Powerwash by one cent in the three-piece format. Sam’s lists the Dawn Powerwash set at $9.98 after $3 off; Costco lists its three-piece set at $9.99 after $3 off. The one-cent gap is noise unless both clubs are equally close. A three-piece cleaning set still becomes clutter when a small household already has an unopened refill. 12

Costco has the wider verified food list today. |
| 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. 2 | Gain + Oxi, 170 oz / 159 loads: $15.98 after $4 off; Dawn set: $9.98 after $3 off; Magic Erasers, 18 ct: $11.98 after $3 off; Downy 39.9 oz: $15.98 after $4 off. 1 | No readable current merchandise coupon row. | Costco for Magic Erasers; Sam’s by one cent for the other three exact or near-exact matches. |
| Electronics | No qualifying two-chain electronics sale row was available. The public Costco page has a dated soundbar markdown, while Sam’s and BJ’s item-level sale prices were not readable. 3 | The public September catalog shows electronics as a covered department, but no item-level electronics Instant Savings price was readable. 4 | No current item-level electronics markdown with a readable price and expiry was verified. | No qualified cross-chain electronics winner. Costco has the actionable single-club soundbar deal. |
| Tires | No qualifying two-chain tire row with complete dates and conditions was available. 5 | No comparable public tire Instant Savings row was verified. | BJ’s current tire page displays separate promotions, but the readable details omit a validity window. 6 | No strict-filter winner. BJ’s displayed amount is a lead to check locally, not a dated comparison. Costco’s $80 offer is the usable published deal. |
| Travel | No qualifying two-chain travel package or voucher price was available. Costco Travel’s current public offer requires a live availability check, while Sam’s has no comparable public price. 7 | No comparable current package price was published in the public Instant Savings catalog. 4 | BJ’s Travel advertises a free upgrade on eligible qualifying cruise sailings, but the public page gives no current sailing price or dated eligible sailing list. 8 | No cross-chain travel winner. Costco has the only actionable package lead, and its price requires a live availability check. |
| Gas | A national Costco average was unavailable. Check the local pump before adding a detour. | A national Sam’s average was unavailable. Plus includes member-only fuel prices and early shopping hours. 9 | BJ’s regular-gas chain average was $3.810 per gallon on Sept. 1. AAA’s national regular average was $4.0954, making BJ’s benchmark 28.54 cents lower. 1011 | BJ’s is the benchmark lead, not a universal winner. Your nearest pump decides the route. |
Costco’s main Warehouse Savings book runs Aug. 24–Sept. 20. Sam’s September Instant Savings catalog runs Aug. 26–Sept. 20, and the official catalog places the current fall book in that window. Costco’s Weekly Warehouse Insider has short-dated rows ending Sept. 6 or Sept. 13. Sam’s current book runs through Sept. 20. 345
The Costco and Sam’s product rows above come from current catalog or item-level deal pages. BJ’s public site shows a Labor Day savings event and a fuel-saver program, but the public merchandise surfaces supplied no item-level price-and-expiry pair that met the strict comparison rule. BJ’s product winners stay withheld rather than turning an unreadable coupon into a guess.
Cherry-picker’s route
Single-stop choice: Costco. Costco is the better one-stop plan for Tuesday because its broad book is already live and its Weekly Warehouse Insider has several Sept. 6 deadlines. Costco also has the only usable Michelin offer and the cheaper Magic Eraser pack.
Use this Costco grab list first:
- Magic Erasers, 18 ct, $10.99 after $3 off, through Sept. 20. 2
- Gain + Oxi, 170 ounces / 159 loads, $15.99 after $4 off, through Sept. 20. 2
- Dino Buddies, 5 pounds, $10.99 after $4 off, through Sept. 20, only if the freezer has room. 2
Add Sam’s Club as the second stop when the list contains Tyson nuggets, Dawn, Gain, or Downy. Sam’s also has Charmin Ultra Soft at $24.38 after $5 off for 32 rolls, but toilet-paper sheet counts and brands vary enough that the figure belongs on a Sam’s grab list, not in a three-way winner row. Premier Protein at $19.97 after $6.67 off for 15 shakes is a good routine-buy signal; keep the checkout total separate from any other pack size. 1
A one- or two-person household should skip the five-pound patties, five-pound nuggets, large candy bags, and 18-box lunch packs unless a specific event or meal plan will use them. A sale price becomes waste when storage, freezer space, or consumption cannot keep up.
Membership math
Use regular renewal fees for the break-even calculation. Acquisition prices can make the first year look cheaper, but they do not set the renewal decision.
Costco Executive: Costco lists Gold Star at $65 and Executive at $130. The upgrade costs $65. At a 2% reward on qualified Costco purchases, the upgrade reaches break-even at about $3,250 in eligible annual spending. Costco lists extra benefits on select Costco Travel products, while gas purchases do not count toward the 2% reward. 12
Sam’s Plus: Sam’s lists Club at $60 and Plus at $120. The $60 upgrade reaches simple reward break-even at $3,000 in qualifying annual spending through the 2% Sam’s Cash benefit. Plus also includes free shipping on orders over $50, free delivery from the club on orders over $50, early shopping hours, and other service benefits. New members can currently pay $25 for Club or $55 for Plus through Sept. 30, but those prices are acquisition terms. 9
BJ’s Club+: BJ’s regular fees are $60 for Club and $120 for Club+. BJ’s describes Club+ as earning 2% back on most BJ’s purchases, which puts the simple reward break-even at about $3,000 in eligible annual spend. BJ’s Gas advertises additional member savings, but the local pump price and the Club+ terms should decide whether the upgrade pays for a particular household. 1314
Next week’s preview
The urgent clock is Sept. 6. Costco’s grass-fed patties, chicken sausages, Bachan’s sauce, and several Weekly Warehouse Insider items end then. The Costco turkey bacon and sparkling-water offers run through Sept. 13, as does the Samsung soundbar offer. Sam’s current Instant Savings book continues through Sept. 20, so next Tuesday’s comparison should start with any local Sam’s price changes and stock limits. 345
This week’s route is simple: Costco for the broadest single stop, Sam’s for the five-pound nugget win and several one-cent household edges, and BJ’s for gas only after the local pump confirms the savings. Costco is not always cheapest; the verified rows this week say exactly where it loses.
