I don't collect all of anything - I buy what I'll use and swap what I won't. At least I try not to (overcollect). I'm tempted to, like, order all the Sweetie Cake glitter pencils once they become available, but then I remember that I'd probably hardly use them and it isn't worth it. :-/

I'm a fairly obsessed OPI collector as well, but I could never get 'em all!
