I never use any off brand products, so in the past, the only products I could get a Sam's were sour cream (Daisy), cream cheese (Philadelphia), eggs, and sugar (Domino).
This week Sam's finally had Gold Medal flour in10 lb bags.
BUT... I use the Domino sugar from Sam's and even though the package is the exact same, the product is far inferior to the grocery store bags. I can only use it in my candy making where i melt it. It has very uneven granules and some are as big as my little fingernail.
The Domino's powdered sugar is the same.
Look closely because the Sam's prices in bulk are often the same prices as Walmart in regular packages. The sugar is an example. Both are about .69/lb.
I haven't used the flour yet, but when I do, I will report if it looks and acts the same.
By the way, Sam's eggs are a good price if you use alot. They are older with an expiration of only about two weeks out for 90. But the price is about $8.00. I go through several hundred a week so it works for me.
