The Best Place to Buy Used iPhones in St. Catharines?

I picked up a 5c at Mobile Tech Xpress used cell phone store in St. Catharines. The cellphone worked great and was in "like new" condition. I was very plesed with the cellphone quality and the price. I also found a case and screen protector in the store. MTX had Urban Armor Gear cases which are hard to find . The people there explained to me how to maintain my new iPhone in regards to proper charging methods and how to locate key components . There was a large amount of phones available in the store and they assisted me in finding a phone that works for me.
