I'm getting ready for a party tomorrow night at my HOA, where I'm going to make up to 15 pizzas on the Blackstone. So I went to Smart & Final (in Costa Mesa, CA) and found Galbani whole milk mozzarella in 5lb blocks for $13.99. The same cheese at Von's in 1 lb. package costs $6 to $7. So the cost savings per lb. is quite significant. If I have some left over I may try freezing it.
Also, for those who like King Arthur AP flour but don't like the price on the 5lb bag, they have a 25lb bag of King Arthur AP for $15. Again that is a very nice discount on the price for the smaller package on a per lb basis. Still twice as expensive as other flours selling in a 25lb bag, but some people don't mind paying a premium for King Arthur. It is a very nice flour.
