has anybody EVER won a prize for doing online surveys for some stores?

[chula]

I started doing online surveys a few months back (Target, Wal-Mart, Home Depot, etc) hoping I will "win" something..but I noticed ever since then I get tons of junk mail saying I won a gift card but when I try to claim it they want me to subscribe for other services or take more surveys. it seems like these surveys are scams so that companies can get your info..I guess I will stop doing them from now on..I thought someone outhere actually won something
