Spar buccleuch

Spar buccleuch, has consistently taken off sell by dates on products and when you return home it is moldy. I have been shopping at this spar for 6 years and it is consistent. I don't know if this is a Spar policy. I have done a test with their cheese, and I have had 4 packets over the years without sell by dates that were full of mould, does Spar think we wont complain.
