Best places to find

Newly lover to juicy, well I guess new old lover as I had them as a teen (if only I knew to hold on to those)

First WHY MUST UK HAVE ALL THE CUTE BAGS 😩

Second, I’ve gotten all of mine from tjmaxx, but if I’m looking to find them elsewhere since I can’t find them in store is Mercari a good place for finds? Or is there a BST in this group?
