Oopbuy Spreadsheet 2026: The Complete Changes Report

The 2026 refresh of the Oopbuy spreadsheet is not a cosmetic update. Real structural changes went in. This is the complete report on what changed, what stayed, and how to adapt your shopping.

Change 1: Stable category IDs

The single biggest change in 2026 is boring on the surface and huge in practice: category IDs are now frozen for the year. Shoes are permanently 911. T-shirts are permanently 913. And so on through 921 for Other Stuff.

Practical impact: bookmarks you save today will still resolve next year. Community QC threads keyed to those IDs no longer break with quarterly re-organizations. Third-party guides can link directly to specific categories without worrying about link rot.

Change 2: Coupon flow moved to parcel submission

In 2025, the shipping coupon had to be applied at product checkout — a confusing timing that caused a lot of failed discount stacks. In 2026, coupon entry moved to the parcel-submission step, right before you pay international shipping.

This is where it should have always lived. See the shipping coupon guide for the updated walkthrough on how this reshapes coupon strategy.

Change 3: QC visibility went per-listing

Before 2026, community QC photos were attached to your order history, not to the listing itself. If you wanted to see other buyers’ QCs of the same product, you had to hunt through Discord threads or ask directly. The 2026 sheet aggregates QCs per listing, right on the listing page.

This is a genuinely big deal for research quality. What used to take 15 minutes of Discord searching now takes 30 seconds of scrolling. Buyers who use the QC finder heavily are the biggest beneficiaries.

Change 4: Category pruning

Roughly 15 percent of 2025’s listings were removed as delisted or unreliable. The remaining 85 percent are all currently in stock or on active restock cycles. The sheet feels smaller in some corners — that is the point. Signal-to-noise went up meaningfully.

Change 5: Rebuilt mobile experience

Mobile category browsing was rebuilt from scratch. Filter chips replace the old vertical accordions, and dropdown positioning no longer overflows on smaller screens. If you tried the Oopbuy sheet on mobile in 2024 and gave up, try again.

Refreshed categories

Jackets, jerseys, and accessories saw the biggest additions in 2026. Underwear was consolidated. Sneakers grew moderately, mostly through new colorways of existing silhouettes.

What did not change

Some things stayed intentionally the same:

• The eleven main categories are the same set as 2025.
• The QC finder tool itself works the same way — just with better underlying data.
• The URL structure of individual listings still uses category-XXX paths.
• Payment methods and cart flow remain familiar.

How to adapt if you shopped in 2025

Three practical steps for returning buyers:

1. Re-scroll the sheet. Pruned listings are gone and fresh restocks are visible. You will find both losses and wins compared to 2025.
2. Re-time your coupon usage. The parcel-submission timing changes when you should be shopping versus shipping.
3. Explore per-listing QC aggregations. Research quality is materially better in 2026. Take advantage.

Should you re-open the sheet?

Yes — even if you shopped in 2025. The category stabilization alone justifies a fresh scroll. Open the homepage and pick any category. If you want the deeper structural background, the complete buyer manual covers how the sheet is built and how to shop it.
