Change shop NotanOtter. We are a family of 6 and we do bulk monthly shopping as well, so I just have to get Fresh stuff from down the road when I need it.
We shop at Morrissons an the thing we take in the biggest Qtty is milk (30 long life litters) it has never been an issue with them.
We just once had a cashier looking at us very surprised "Is that your weekly shopping" (I am a bit overweight but...) To wich I replied "It is monthly and what is it to you?".
I do not think it is the place of the cashier to comment on your shopping and the stupid number of goods limit really baffles me,as they do not know your circomstances. What if you are buying for a school event or if like a lot uf us you have a large family, It is not their business, as long as you pay for it!
