Returning something you don’t want
You do not have an automatic right to a refund when returning something you bought in a shop because you have changed your mind.
If there is nothing wrong with the item (for example, there is no fault) you have no legal right to return the goods. Whether or not you can get your money back depends on the seller’s returns policy.
However, many sellers voluntarily allow customers to return or replace goods during a certain time period. The seller may offer a refund, exchange or credit note as a goodwill gesture. Check what the seller’s returns policy is before you buy.
