I'm a bit fed up with swipping my store card only to discover I missed out on any discount because I didn't pre-select the discount. M&S are the worst and I now realise Co-op are doing it too. If you have a store card and swipe it surely you should get the bloody offers that are on. I think it's a trick and at a time when everything is getting so expensive the least the supermarkets could do is give their card holders the offers. Totally bugs me!!
