Apple Gift Card

I have couple of Apple Gift Cards totalling up to $500 CAD. I like to sell them in exchange for cash or prepaid visa/mastercard. You can buy all of them together or individually. I am expecting it $5 less $50 and $10 less for $100 gift cards. I bought them for my Apple Watch but ended up buying from other store because of a discount.
