My BF found me so much dirt cheap resale merch when he went to Japan it was insane. He was buying me keychains for 50 cents!

The merch there is very cheap, even at resale shops, but I gotta scour Yahoo auctions and HOPE a single standee or keychain drops below $150USD it's so sad :/ I'd love to go to Japan for several reasons but it must be so insane to find rare doujins or whatever for less than $10 USD. Unfathomable.
