I made the foolish mistake of buying a grab bag from Lolita Kisama. Actually, I think buying anything from them in the first place is a foolish mistake, but that's an entirely separate rant. xD
As people mentioned, it really did feel like they just threw in a bunch of cheap stuff no one cares about and then slapped a cool title on the bag (I got the 'Visu Kei' bag) hoping someone would fall for it and, furthermore, be fooled by the 'deal' they are getting on overall retail price.
No, seriously, waste of money. All it was was a bunch of cheaply made 'omg we're gawth' accessories that one could probably find in a random prize game at the arcade. Wtf? They throw in a strip of white cloth, call it a noseband, and they'll say you're getting a deal 'cause normally they'll charge you like five dollars for something you could rip off of your old bedsheet.
Oh, that's riiiight...if I had a five dollar strip of cloth, I culd be just liek Reita~!!!111!!1!
Sorry, that was a bit of a mini rant. xD I guess to sum it up, my experience w/ grab bags has been -23,428 on the one to ten scale, but then, that was LoliKisa so what's to be expected.
As a sidenote, don't buy stuff there. It's amazingly overpriced. And they're not even 'speshul imports from Japanz.' =__=
