Beware of a bait and price switching: I had a very disappointing experience today. I took several items to the register some with tags on them and some without. The lady at the register told me she had to ask the manager about the price of two items because she was sure it was not regular price of $4 -$6. (Mind you they are working with DONATIONS!!!)... the manage took the items to the back of the store and after 10min wait he returned with new prices on the items....one piece jumped from $4 to $11 and the other piece jumped up to $6 - $30. His justification for the price change was that the "items were new and their tags must have fallen off." They are ridiculous and I will not be returning because I am afaird of a bait and switch!!!.
