[feature] Lowest price in "group" feature

[dgtlmoon]

Cool idea so you can see which web page/link in a list of product pages is the lowest (or highest) price

In the groups overview page, if any items in each group contain a restock/price check, then it should check all items in the group and show you which link has the lowest price

So for example you want to watch 10 of the same "widget" in 10 web page/stores, and you can see which one is the lowest

I guess this means a new type of notification for the group too.. hmm
