Yes, but it'll probably cost you a tenner.
Under the provisions of the Data Protection Act, you have the right to access any data about you held by a retailer.
You should make your request in writing, marking the letter for the attention of the Data Controller. (I strongly recommend keeping a copy and using recorded delivery). The retailer has the right to charge an administration fee - the maximum fee permissible is �10. (It might be worth phoning first to ascertain this fee, in order that you can enclose it with your letter). The retailer must provide the information within 40 days.
The above is a summary of the legal position. Full details are available from this government website:
