As said above if you buy online you can change your mind within 7 days under the distance selling regulations. Legally the club would have to refund you. If you purchase in store at the business premise the club dont have a legal requirement to refund you unless the goods are faulty or not of satisfactory quality (this is open for interpretation). Most businesses will still refund if you have proof of purchase as they see it as best practice. However it would be up to ecfc.
