good luck with that
That was an example only... £11 at Waitrose currently, therefore £9.90 cost, Most weeks one of the other supermarkets will be at £10, therefore you stock up when it is.
only problem with your theory is that the cheapest comparison is £12
Comparison shops are talked here dozens of times a day throughout different threads, those that do then reap the benefits, however I'd suggest the majority can't be arsed as they assume it's hard work even after people take the time to explain. If you don't have an Asda where you could shop at then it's irrelevant. If you do, just do a simple comparison shop ensuring that one of the other supermarkets is selling the product (and other products you choose to buy) cheaper or at the same price. ASDA £13 Tes or Sain or Morr £10... buy at A in a comparison shop, A give an extra 10 %, therefore £9
if you are able to get £9.00 then please do share. I am sure we would all like to know.,
