I know they can be really cheap, but most stuff doesn't last or work as strongly as others you'd buy from a grocery or dept store.
I went in the other day for garage sale tags.
I noticed they had canned artichokes. (I love them) for $1.00!!
They are normally $2.99 from my grocery store, I bought the last 6 off the shelf!
So what do you buy when you do shop dollar stores?
