Put down the keychain/shot glass/snow globe and waalllk awaaayyyy...

Souvenirs are almost always an impractical waste of money. You buy some stupid junk, give it to someone (or keep it, you selfish bastard), and then it either sits on a shelf and collects dust or it gets chucked in a box or closet or whatever - never to be seen again. Or it gets thrown away. Dumb. I hate souvenirs (unless they serve some actual purpose, which is pretty much never true). If anyone ever thinks about buying me one, thanks--that's very sweet--but save it. The best souvenir ever will ALWAYS be a picture (or a lot of pictures).
