I think some of the chain stores have worked "deals" with genuine TIGI product dealers. But, there are some fakers out there, too. If the product looks weird on the shelf (like it needs to be shaken), smells funny, or in general seems to be different, then I'd go somewhere else.

I used to live in Alaska, and I would call a salon somewhere and have them mail my TIGI to me, so you can go that route, too. It is not like it sells for less $$ at the chain stores, anyway...
