Since I started couponing, I have only shopped at Sam's Club once. Before this summer, we were shopping there at least 2 times a month. I would always buy things at Sam's that we could not afford in regular quantities at Publix or Target. However, I have found that with couponing I can now get those items for significantly cheaper per item or per unit than I ever could at Sam's.
Here is an interesting price comparison that one of the couponing blogs I read has on buying items at a regular grocery store with coupons versus buying them in bulk at Sam's or Costco.
Kinda makes you think about what a good deal really is, doesn't it?
