They still have a slim range of CDs and DVDs in my local store. Mainly compilations, budget Gold releases and a the odd slightly random new offering. Their selections lean very Radio 2 - I don't think I have even seen Olivia Rodrigo's perennial number one album stocked, though the latest Texas effort made the cut.
Going back a few years they had a whole aisle until Argos moved in. To be fair when I do pop round to have a look there is never anyone else browsing.
I wonder how many of the Now series sales come from the supermarkets too?
