Make a grocery list, and stick to your list. Whether you go to Aldi, Walmart, Target, Giant, Costco, or any other place, you will blow your budget if you do not stick to your list. Do not get into the mindset of overbuying because you may end up with a pantry of unused food. Do not get into the mindset of, "Well this is on sale...I just got to get it!" You will overspend. If you are going somewhere that sells things other than food, put the other merchandise you need on your list. If it is not on the list, don't buy it.
