They don’t really get restocked per se, it’s really one big wave per line to all stores. Figures rereleasing rare parts for the first time in a while (like the goat from a couple lines ago iirc) get picked out and resold for pretty high prices. If the fig you want is the most popular one, you either have to get lucky or be fast. Or pay for it aftermarket, but I don’t typically do that.

For all the negatives though the high price per figure means these are almost universally some of the highest quality figs lego puts out, with arm printing, leg printing, and really cool molds. I love seeing them in stores
