Produce picks (if they look good), milk, eggs, cheeses, butter, pretzel rods, dried cranberries, stuffed shells/manicotti (the kind we like is seasonal, so we only get it in season), flour, sugar, olive oil, salt, baking powder/baking soda/cornstarch, popsicles, tortillas and taco seasoning, beer bread mix, some seasonal items (apple butter, canned pumpkin, etc).
I avoid - junk food (other than pretzel rods and choco covered pretzels, which I'll buy as a treat) - just don't like the generic's taste and the name brands can be cheaper elsewhere, meat and lunch meat - better deals and tastes from grocery, cereal - not enough options, beverages - better and cheaper at local grocery and they don't carry what we like, frozen foods (other than the Italian ones) - again, not a huge fan of them and can find better at local grocery, all toiletries/cleaning products/paper products (except wet wipes) - I stick to paper, not foam, and I am picky on cleaning products, so I don't buy these, either, baking mixes (except beer bread) - family just didn't like them more than my own recipes.
Aldi is my "every 3 weeks" store, when I run out of staples and the 3 tubs of pretzel rods I buy and the produce picks are my favorites...I usually spend $100 there stocking up, but still have to spend $50-$75 at the local grocery to finish the week.
