Some stores are using increasingly strict but conventional means to curb returns. Items such as computers, digital cameras, and opened goods may be subject to limited return rights, restocking fees, shortened return periods, or no refunds at all.
Here's some advice on return those unwanted gifts from Consumer World.Org.
Wait ---but not in line today, in January. In most cases you'll have thirty days to return your item, but it's good to check the return policy.
To improve your chances of getting a full refund, provide a sales slip or gift receipt, and return the item in new condition, unopened, and with all original packaging material.
Returns without a receipt are subject to the retailer's posted return policy, which might result in receiving only a merchandise credit for the lowest price the item has sold for in recent weeks, or possibly no refund or exchange at all.
