24/12/11 17:52 #13. I returned an item yesterday and the shop refunded it back onto my credit card, how long will it take to go back on? Depends on the retailer and also your credit card company. I've had credit card refunds back on my card the next working day, but it's usually a few working days. From a legal point of view, once a refund has been agreed, they have 30 days under the Sale of Goods Act to refund you.
