Always a good buy!

Sam's Club
Have a look at www.samsclub.com. The 96th St. location in Indianapolis is closest. You can even place your order ahead of time and they'll shop for you and bring it to the door.
~Hamburger - 90% lean $2.20/lb. (Comes in 8 lb. tube. I divide it into 16 1/2 lb. sections, put in freezer bags, smoosh flat and seal. When flattened in freezer bag, it can thaw very quickly.)
If you have a deep freezer and can afford it, they offer 80 lbs. for $140.00 or $1.76/lb. It's very lean and tasty meat.
~Butter - $6.90 for 4 lbs. or $1.72/lb.
~Bread -varies but 2 - 100% whole wheat loaves are $2.48
~Cheese 5 lbs. of cheddar for $12.74 ($2.55/lb.) or 5 lbs. of mozzerella for $12.28 ($2.45/lb.)
(Divide into five freezer bags and freeze until you need it.)
~Folgers coffee - 52 oz. $8.56
~Starbucks whole bean - 40 oz. $19.82
~Hawaiian blend whole bean coffee - 40 oz. $12.82 (My personal favorite and one splurge at the grocery store - best "good" coffee for the money.)
~Huggies size 3 diapers - 200 for $36.59 (or member's mark - 200 for $30.88)
~Huggies wipes - 720 for $14.86
~Malt O Meal Honey Nut cereal - 44 oz. for $2.76
~Clover Honey - 5 lbs/$7.39
~Yeast 2/16 oz. bags $4.16 (Lasts six months when making bread on a regular basis.)
~Vanilla Extract 16 oz. for $6.88

Aldi
Great place to get all your staples. The vast majority of their products are comparable to name brand items. The few items that I don't care for include their meats, paper products, and some of their fresh fruit.
~Milk - Never goes over $3/gal. Stays around $2.79
~Eggs - Always cheaper than anywhere else. Right now (April 2008): Large $1.79
~Chili beans - Tasty and less than $.50/can
~Pintos - $1.60 for 2 lbs.
~Parmesan Cheese - $1.79 jar
~Dishwasher detergent powder $1.49/box (as good as Cascade, in my opinion)
~Canned veggies - $.44/can
~Sugar $1.79
~Flour $1.44
~Powdered/Brown sugar $.99
~Potatoes $2.50/10 lbs.
~Baby Carrots $.99/lb.
~Frozen Veggies $.88/bag

Marsh
I only shop Marsh's sales. However, they always have one brand or another of bread on sale. They also usually have good sales on laundry and dish supplies. And, Marsh is the only place that I will buy sausage.
~Sausage - lean, freshly made. It's the best sausage I've ever had! And it's only $2.50/lb.
they have Hot Italian, Italian, Country, and plain ground pork. They also make fresh brats.

Walmart
I do not do the majority of my shopping at Walmart, but that's just because I shop so many different stores. Some weeks it's more than others. However, If I were going to shop only one store, it would be Walmart. They have consistently lower prices over all. The only way to beat them is to shop at a variety of stores and hit their sales.
~Seasonings - $.50
Italian, cinnamon, onion powder, garlic powder and other common seasonings.

Meijer
Great deals on weekly specials. They seem to have the most variety of foods on sale.
~Free antibiotics (certain generics)
