I like to buy items in bulk. It is not cheaper on all things but on some things it is quite a savings. For example we like homemade pizza. Pepperoni is my husband favorite type of pizza. Pepperoni is expensive and not an item I see on sale very often. Yes, we could do without pepperoni, but I like to try to fit items my husband likes into the budget. I have found that I can do this by buying some things in bulk. Pepperoni is one of them.
I buy it in a 5 lb package at Sam’s Club. Yes, I know that is a lot of pepperoni. For us about a years worth. But it only cost me $11.57. I wrap it up in individual packages and freeze it. I get about 18 packages which is about 18 meals. I usually use 1 package for two homemade pizzas which for us is a dinner and lunch for my husband the next day. This makes pepperoni much more affordable. It is much more than this per package at the grocery stores.
