Michigan has a 10 cent bottle deposit.

When each can or bottle is worth 10 cents at a local store or supermarket, you tend to not throw them away nearly as often - in fact, you very rarely see litter in the form of bottles or cans. It is very effective in controlling litter, though when $2.40 is added to a case of pop, it is rather annoying.

After growing up there, it was really tough for me at college, where they didn't have can recycling for the first year I was there - it was next to impossible for me to actually throw them in the trash.

I am in favor of a national bottle deposit.
