Man of Honour
My shopping strategy has been the same no matter what supermarket.
Don't use a trolley, only use a hand basket. The end result is there is only so much you can carry in the basket, both in volume and in weight. It always cost between £15-£25 no matter where I shop
Has been doing that since uni days.
When I nip into Waitrose on my way home from work I don't even pick up a basket, I can still manage to spend £20 on stuff that fits purely into my helmet which isn't much even with my massive head.
I can fill a basket in Aldi and not even break the £20 barrier.
