I don't blame you there, I think a lot of people are feeling that way. I had to join a discord with a bot that pings everyone when they get stuff in stock to even have a decent chance to acquire stuff that's exclusive to their shop.

Though, it seems like they've been making a shit ton of pops for their shock drops. Probably about 80-85 percent of their exclusives to the Funko Shop have sat in stock for days or even weeks before selling out lately. Fastest thing I've even seen sell out recently was GITD Shredder, which took like 16 hours.
