$90 Canadian Tire Gift card

I bought an air fryer that was defective and unfortunately they only give in store credit for open box returns. I changed my mind on the air fryer and wanted to get a smaller one, so now I have $93.22 on a gift card but I don't want in store credit, I just want cash for it (like I originally paid) but will have to settle for trying to sell this gift card instead. I'm asking $70 for it.
