I recently went to my nearest Lidl and Aldi on a shopping trip with the hope of picking up some bargains as I had heard they were so much cheaper than the mainstream supermarkets.
I was a bit surprised to see that the stuff they have is quite random and I didn't find it much cheaper than the other supermarkets. Perhaps a few pence but nothing to write home about and some of it was definitely the same price. Sure, things like Lidl's nappies are cheaper but I just waited a few days until Sainsbury's/Tesco's have an offer on and got a load of Huggies nappies cheaper than Lidl's. Perhaps it's just a case of not buying expensive brands (except when they are on offer) and looking for offers/bargains at the big supermarkets?
