yep dollar store, Wal-Mart, Kmart, target, Rid Aide, Longs, in the party section.
We have to use them for our daughter, she is autisitc and will not go on the dark rides with out them. They are great for that. Just buy a bunch, they have the bracelets too. I have even inter locked them in Georgias pony holder or bows! she thinks that is the neatest thing ever. She will just look at her self in the mirror for hours with that. hahaha
