Just go to a couple different stores. Only stores in my town that card you are wal-greens and hy-vee. If a store cards you, say "oh. why? I don't think I have it on me to be honest" and move on to another store. They aren't gonna call the police and be like 'some kid just tried to buy dxm'. They don't care that much.

Probably a better idea then stealing it which could get you in some shit.
