Where can I go for used cell phones in St Catharines?

My husband and I bought a used cell phone a few days ago for our niece . She has been asking us for a new Samsung Galaxy Note and we thought it would make an awesome Christmas gift . We went to MTX on Merritt in St. Catharines to inquire about one. MTX had several different Samsung phones for sale and happened to have one Samsung Galaxy Note available. We grabbed the cellphone and were given a 90 day warranty. The staff also assisted us in choosing a cover and screen protctor. We were very happy with the quality of service we received and we can't wait to see her face when she receives her present. Thank you MTX staff
