Cheep souvenirs i can find in ALL 48 Continental states?

I've a perfect one for you! I collect fridge-magnets, yeah some people think they're tacky but they're a constant reminder to me of the places that I've been to and the good times that I've had. They're also relatively light-weight and cost on average $4 a pop, but you can get ones cheaper. They'll last you a life-time and all your friends can spend hours in front of the fridge! You can also buy ones that have a space for a photograph in them so you can take a pic of you and your gf's in that state. Hope that helps!
