We go to Aldi, Walmart, Trader Joes & the local IGA mostly for groceries. I'm also lucky I have a bulk food store close to me for buying basics which are fresher than the big stores.
My local IGA has some higher prices than Aldi & Walmart, but they are cheaper than Kroger's & Meijers. The deli is reasonable with a good selection of meats, salads, cheese, breads & great rotisserie chicken. They also make in store subs which are loaded with meat that we like. The only thing I get from Krogers is dry kitten food & Meijer is cosequin for my one cat.
I find that buying basic ingredients & cooking from scratch is a lot cheaper than buying pre-packaged foods. I can also control what goes in them. The only "processed" foods we buy are things like condiments & some pickles.
This summer I hope I will have more time to do canning than what I did last year. I make all of our jams along with savory ketchup & dilly beans.
I've noticed items going up in price & found alternatives to them. I switched from Hellman mayo to Aldi's. I also like that Aldi has organic that isn't unreasonable to buy like their ketchup. Aldi's butter is also pretty good.
