I was on the road last week in the boondocks. Walmart had so many kosher items with national hashgachos it was unbelievable. Even mozzarella cheese, bread, etc. If you don’t keep CY or PY, you can save a lot by shopping in regular stores. A can of beans is a can of beans.
Shoprite stores in nj with kosher sections have prepared goods under ou hashgacha at an insanely low price.
