- Whatnot auction buyers setting item-by-item bid limits
- Worth noticing
- The browser extension uses eBay sold searches through the buyer’s own signed-in account; each comparison can be opened for verification.
Field notes
The page provides a manual search option alongside stream sharing, so buyers need not rely solely on seller announcements. Its extension setup is hands-on: users download it, enable Chrome or Edge Developer mode, load the unpacked folder, and stay signed in to eBay. The page describes an upcoming-items queue and a session log, though both are empty in the captured view.
