How much is the maximum credit in the shop? Isn’t it $25?

Isn’t it $25 and then it’ll stop accumulating? I’ve been at $20 for the past month and i’ve been waiting till i get my $5 more so i can get the Eddington 4k but it still hasn’t showed up yet

did they change it to $20? or do i have to wait a few more days? i’m confused lol
