Most changelogs read like release notes for software you do not care about. The 2026 refresh of the Oopbuy spreadsheet deserves close reading — five changes materially affect how the sheet gets used.
Change 1: Stable category IDs
Category identifiers are now frozen. Shoes are 911. T-shirts are 913. And so on through 921 for Other Stuff. Bookmarks made this year still resolve next year. Community QC threads keyed to those IDs no longer break with reshuffles.
Change 2: Coupon flow relocation
In 2025 the shipping coupon applied at product checkout — a confusing timing that caused failed discount stacks. In 2026 the coupon step moved to parcel submission. See the layered discount guide for how this reshapes strategy.

Change 3: Per-listing QC aggregation
Before 2026, community QC photos attached to order history. Researching a listing required hunting Discord threads. The 2026 sheet aggregates QCs on the listing page. Massive research quality improvement.
Change 4: Category pruning
Roughly 15 percent of 2025 listings were removed as delisted or unreliable. The remaining 85 percent are in stock or on active restock cycles. Signal-to-noise went up.
Change 5: Mobile rebuild
Category browsing on phones was rebuilt from scratch. Filter chips replaced accordions; dropdowns no longer overflow. Mobile shopping went from unusable to genuinely usable.
What pointedly did not change
- The eleven main categories remain the same set.
- The QC finder tool works the same way — with better underlying data.
- Listing URL structure still uses category-XXX paths.
Should you re-open the sheet?
Yes, even if you shopped in 2025. Category stabilization alone justifies a fresh scroll. Open the homepage. For structural background, read the onboarding blueprint.
