I have a transaction on my account that I didn’t make at Sainsburys, could I have been defrauded?

As I mentioned in the question I was checking my apple payde account today and saw a Sainsburys transaction last week for exactly amount of £65. After checking everything (pictures, messages, shopping receipts) I am sure that I was not there at the time of the transaction. Also the place where the procedure was done seems to be somewhere in Enniskillen, Northern Ireland (and I have never been to Northern Ireland and it is a 9 hour drive from here lol. Has this ever happened to anyone before? Could I have been scammed or my card details stolen? I cancelled my card as a security precaution but this has me worried.
