Any comments, please?
For example how do you get a 25% savings in food costs? It looks like you can get some non-perishables at about the same cost as the super market ($45 free shipping at Walmart, Amazon food subscriptions), but you would still have to make the same number of grocery trips--because grocery trips are determined by the need for perishables.
I suppose the article writer was thinking about all the great coupons you can get--but these coupons are seldom for basic foodstuffs for cooking from scratch.
So tell us; how do you do it?
