Just a word to the wise...make sure you DO do comparison shopping when shopping at Aldi. A friend of mine who's dh lost his job two weeks ago did this today. She was shocked (and so was I!) to find that milk was $.40 MORE there, grapes were $.03 more, and a few other things. Overall, it DOES save money on a ton of items, but it is a really good idea to keep a notebook in your purse to write down and compare prices when shopping!!!
That said....my favorite is the little things that add up to big prices. Five of my six pack lunches....so I have to buy a lot of that kind of stuff. Yogurt is a biggie...almost half the cost of Walmart!! Sandwich meat...the GOOD stuff....double the package for cheaper! Oh..and the biggest is probably BREAD. We never buy bread anywhere else now. This includes bagels, english muffins, buns, etc. They have GREAT deals there!!
