Just environmental damage- $0.25. By the way, you're also playing monopoly? I've received about 30 of those tickets while buying stuff, and still haven't won anything.
I've gone through prob 200 monopoly pieces and won organic tea and a bottle of water so don't feel bad.
Just last year, the Safeway staff at the store near me gave away so few tickets (and apparently too few people were playing), so around the middle of May (towards the end of the monopoly game), I got a got a whole box of tickets. After going through an entire box over the weekend, I can't tell you how many cans of tomato sauce I won.
