Per Doreen's request, I'm in the lower Susquehanna Valley, Pa, USA. Other parts of Pa may have very different prices.

The cut rate store I used in the example list is Aldi - most of their prices are pretty consistent, and they don't put many items on sale from week to week. I was there today though, and...

eggs $1.25
block cheese $1.69
packages of deli sliced cheese $1.79
Heavy cream $1.50.

While I was there, I also bought

whole milk plain greek yogurt - $3.49/quart
2 lb bag of frozen tilapia $5.49 ($2.25/lb)
head of cauliflower (about 8" in diameter) $2.39
Deluxe American Slices (NOT the individually wrapped junk - these are the old fashioned slices that you peel off the stack - it's real cheese, melts nicely) $2.79
green onions (at least 15 in the package) 95 cents
