Since the subject seems to have come up lately:

• Thinkgeek Wishlist
• Amazon Wishlist (I know, there are valid reasons not to patronize Amazon. You’re not even remotely required to buy anything from them, mind you, but it’s the only place I have access to all of the music, books and videos I want all in one storefront, so that’s where I keep the wishlist.)
• Funagain Games Wishlist

This entry may be updated if I find somewhere else that I should have made a list… and/or checked it twice…
