Tomorrow, both Savers and the Unique family of thrift stores are having one-day sales. At Savers, club card members will save 30% on clothing, shoes, accessories and goodies in the bed and bath department. (You can find the store nearest you here.) Customers visiting Unique thrift stores (and Valu thrift in St. Paul) will get a hefty 50% discount on clothing, shoes, accessories and bed and bath supplies, but only if you have an I M Unique card. (You can find a complete list of their locations here.) Signing up for both savings clubs is totally free…just don’t try to register for an account on a sale day. That’s a no-no.
