Here in the Mountain West we have Associated Food Stores which go by a various names such as Macey's, Dan's, etc. Because of the culture of food storage here Associated Food Stores have yearly food storage case lot sales which has food deeply discounted for about two weeks when one buys in bulk. Each year I, and many of our other beekeepers, make sure to buy our sugar during the sale. This year I was able to pick up white sugar in 50 pound bags at a cost of about 37 cents per pound. Needless to say I buy hundreds of pounds at a time. It is also a great time to buy bulk containers such as food grade buckets and 5, 10, 35, and 55 gallon food grade liquid containers at a steep discount.
