Just anecdotal and I am sure someone has studied it, but when Aldi came to our town, the prices of things that stick in your mind and are often advertised when down at the other grocery stores to match Aldi. So eggs and milk are not the best things to track unless you are looking at wholesale because they can be loss leaders. Aldis does have great prices on almost everything you need for groceries though. My last comment is that it always seems that the prices of things we want/need to buy go up way faster than inflation. At least my mortgage hasn't gone up.
