For home I buy cream, lunchmeat & cheese (I have a slicer) Potatoes sometimes, Keilbasa, bacon, Gyro meat. For business I buy red wine vinegar, spices, some produce, fresh herbs & some kitchen supplies like gloves.
The real deal @ RD is when you find something they want to get rid of. For example: They got stuck with a case of a dozen Ring Baloneys (a local delicacy) & I bought a case of 12 for $18. It freezes well. Last month I got a whole (16#) brisket for $1.89/#. On Monday I picked up a 4# tub of tuna salad for half price. Exp date is the 27th but I have to take lunch every day this week so it’ll be gone.
Ripped bags of produce like potatoes go for half price & I’ve bought those on occasion also.
I also buy chicken for the dog there. I pay anywhere from $.89/# to $1.09/#. I buy it buy the 40# case but we have a big freezer. If fresh boneless breast is on sale I separate one 10# bag into individuals & freeze them for the humans. Last month whole pork loins were on sale for $1.57/# which is a good price but I was already stocked up. When I buy one I slice pork chops out of the middle & save the ends for roasts.
