The whole process of turning my unwanted £75 M&S gift card into cash was extremely straight-forward. I've never 'sold' a giftcard before so I looked on the internet and found CardYard who sounded trustworthy and offered a good price for my card of £60 and a few pennies. I thought 20% was a very fair and reasonable rate to ask for the service. I simply registered on their site, entered the details of the gift card and sent it off to them. I got the cash paid directly into my PayPal account within 2 weeks as they need to check the card is valid and saleable. Card Yard kept me informed by emails at all points in the process as to what was happening with my card: when they'd received it, when they'd checked it and when my money would be received. It was really excellent - couldn't have gone any better.
