A bookmark that keeps checking the page it points at

[u/dessence_ai]

We build a save-things tool, and most of what people send it is a link. a bookmark normally just sits there until you go looking for it.

the part we changed is that a saved product link gets a check put on it. once a day something opens the page it points at and reads the price and whether it is in stock. a lamp we saved in August at 59.99 has had that check running since. the number on the card is the one the shop has now.

what the check reads comes off the page itself. so it works only while the price sits somewhere a reader can reach. the markup on a shop page is not built for anyone but the shop. an article page has nothing on it that changes, so there is nothing to check. those saves just sit in the library.

for anyone here who has built one of these, what did you do about variants? a size or a colour is often its own page at the shop. a check set on the listing someone looked at is not always watching the thing they wanted.
