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

My husband and I purchased a used phone a week ago for our niece . She has been asking us for a new Samsung Galaxy Note and we thought it would make an awesome Birthday gift. We went into MTX on Merritt in St. Catharines to inquire about one. Mobile Tech Xpress had a few different Samsung phones for sale and only had one Samsung Galaxy Note available. We grabbed the cellphone and received a 90 day warranty. The staff also assisted us in choosing a case and screen protctor. We were very pleased with the service we received and we can't wait to see her face when she opens her gift Thank you Mobile Tech Xpress
