- Pokémon card buyers scanning eBay in Canada and the US
- Worth noticing
- Watches run only while the browser tab is visible; the site says they pause in the background and are not an unattended alert service.
Field notes
Filters distinguish listing-level limits, such as item price, from profit and landed-cost filters applied to the feed; candidates with unknown costs can remain visible for review. The lot workbench says hidden or unreadable cards count as C$0 and asks users to count each physical card once. Saved watches are browser-based, and the page warns that they stop scanning when the tab is in the background.
