Normally this discount 'Diamond' card (for the over 60s) applies on
Wednesday only. However, we've used it this month on other days - as
they have another thing going with the 'Privilage' card which is being
accepted as 10% discount on all days in May and has probably got a
similar setup on B&Q's store tills (except the cashier is not reminded
to look at the purchaser to ensure he/she is of qualifying age!).
