Ever wanted to avoid Kijiji.ca or Ebay.ca and just go to your local Rogers store and trade your old phone for cash. Now you can. Of course the trade-in value is not as high as you would get on the website mentioned above, however there are no hassles. As long as the screen is responsive, the phone powers up and it actually works, you will get the cash.
Some common devices/prices:
Rogers iPhone 4 (16GB) = $90.00
Rogers iPhone 4S (16GB) = $185.00
Rogers iPhone 5 (16GB) = $280.00
Samsung S4 = $160.00
Blackberry Z10 = $150.00
