It pays to listen to your elders! Just yesterday I met up with an older neighbor at the library. She gave me a heads up on two discount grocery stores in our area and suggested I give them a try. I didn't know about either one of them. Since they were across the street from each other and less than a mile from the store I had intended to go to, I decided to check them out.
My first stop was Sav A Lot, http://www.save-a-lot.com/ Bananas were $.29/pound, a gallon of white vinegar was $.99, toilet paper $.49/1000 sheet roll. (Bananas are the one fruit I compromise on and buy non-organic sometimes.) There were some other good prices but all on stuff I don't buy. I do remember a time when I would have been tempted by the cheap cereal.
My next stop was Price Rite, I couldn't find a website when I did a google search. I'd check the phone book if I were you because they had half gallons of Silk for $2.49! That made the trip worthwhile!
Both these stores, as well as Aldi's charge for bags. All have box bottoms that you can use for free stacked in front of the store. I just throw my canvas bags in the car and transfer from shopping cart into them.
