Amazon is always the first place I check since it's the most reliable to buy stuff online. That and you can get free shipping on orders over $25. More incentive!
Hehe. That's why my dad likes to go too. Most of the time though they don't have stuff I'd like to try sample wise. >.<
The only reason I know about some is that I'd watch them with my grandma. She has a bunch of old movies, but they're still good. There's something about that old feeling of things being so much simpler in those times that attracts me.
