Liquidating a Target gift card into my Paypal account: what fees?

So, I was recently given a gift card for Christmas to Target. I really hate shopping at Target due to everything being so overpriced. I was considering liquidating my Target gift card into cash by buying a Visa Prepaid Card at Target for 50 Dollars, and creating some random 50 dollar listing on Ebay and buying it with my Visa gift card so the money goes into my paypal account. What am I looking at in fees for the activation and the ebay listing fees?
