Where can I go to buy used cell phones in St Catharines?

My husband and I grabbed a used cellphone a few days ago for our daughter . She has been begging us for a new Samsung Galaxy Note and we thought it would make the perfect Christmas gift . We decided to go into Mobile Tech Xpress on Merritt in St. Catharines to inquire about one. MTX had several different Samsung phones for sale and only had one Samsung Galaxy Note available. We were sold! phone and were given a 90 day warranty. The staff also assisted us in choosing a otter box and screen protctor. We were very satisfied with the service we received and we can't wait to see her reaction when she receives her present. Thank you MTX
