Hey Bob
I just tried checking Fiorot's math on Gordon's Food Service Store pricing for Grande Cheese...
The folks at the nearest store to me confirmed that they could get Grande, but as others have mentioned only in full case lots, and for our Shredded Grande 50/50 that means 6 five pound bags for 30 pounds total. The price was $109.95, and they needed a few days to get it to their store. That comes out to $18.325 per five pound bag, and that only works if you have friends and family to help buy and store some of the 30 pounds of cheese in that full case box.
I guess if you can find a GFS store within driving range and plan a few days ahead with those pizza loving friends and family, you can get Grande cheese for $3.665 per pound.
Enjoy!
