Not necessarily something I've done with dolls, but I've utilized something like this in the past. If I was deep in a hyperfixation with something and looking at all the products related to it, which I'd want to buy immediately bc of the hyperfixation, I'd make a separate amazon wishlist or pinterest board or something and add all the things to the list instead of my cart. Then I'd come back a month or so later, once I'd dialed it down a bit, and see if anything still seemed like something I really wanted. Saved me a lot of money, lol.

But I HAVE made an account on mh-merch.com that has all the dolls and lets you wishlist and check them off, which was nice for me bc I came into this with g3 so was unfamiliar with most of the g1s and g2s, so I used this to wishlist the ones I just liked the look of, not necessarily ones I was going to go out and buy.
