You could reach to Telus and see what can be done. As for as I know they had a $300 Visa gift card and $200 promo going on.
Worst case scenario sell it for face value. Twitter usually garners the faster response reaching Telus.
In case anybody is interested, I can paypal you $190 for a $200 steam gift card. I can even pay through friends and family so you don't have to pay any fees.

Paypal has been used in countless scams where the purchaser claims a problem with what they were sold, and gets what they paid refunded. The seller is left without both the cash and the item being sold.
