Shopping in the sales
You have the same rights shopping in the sales as you do at any other time of the year.
Items sold in a sale should be of merchantable quality, fit for their intended purpose and as described to you. If an item is faulty, your rights do not change just because it was on sale. You are entitled to return it and seek a refund or exchange to the value you paid, e.g. the sale price. However, if the item was marked down because of a fault, and this was pointed out to you at the time, you may not be entitled to a refund or exchange. If you bought something at full price which turns out to be faulty, and it is now on sale at a reduced price, you are entitled to a refund of the full price you paid or a replacement of the same value, with proof of purchase. If you buy something at full price but change your mind about it, and it is now on sale at a lower price, you may only get the reduced amount if the shop is willing to offer a refund. Any offer of a refund in this situation is at the discretion of the retailer and is a gesture of goodwill.
Remember, whether there is a sale or not, you are not automatically entitled to a refund or exchange if you simply change your mind. The shop’s own returns policy may be different when something is bought in a sale, so check the policy with them before buying if you think there is a chance you might change your mind.
