The concept of this store is really cool. You bring in a bag of clothes (or if you only have a few items, you are welcome to bring those in too) and pay $20. Then, you get to fill up you bag with anything you want from the store. You get however much you bring. Upshift does not buy any product from outside vendor; all the merchandise in their store is from their customers. The store itself is very small and cramped. The clothes are very loosely organized by color and size. There are two changing rooms and not really a good way to tell if someone is using them or not. On the first Thursday of every month, they do a 2 for 1 special where if you bring a friend, she can get in for free (or you each pay $10). They do also purport to offer free Franzia to shoppers, although I did not partake.
The selection is about on par with what you would find at Goodwill or St. Vinny's. If you bring in clothing/accessories and don't find anything that day or don't have time to shop, they will give you a credit that you can use on a future date. Worth checking out at least once. Buy local!
