Sam’s Club will be having a free weekend August 2-4 where non-members can get the same prices as members. You will need to register at the Customer Service counter to receive a one-day pass.
If you are not a Sam’s Club member, this may be a good time to check out and see if the membership would work for your family. Some items may be a better deal in larger quantities but you need to determine if you will be able to use it before it goes bad. You will not be saving money, if you end up throwing quite a bit of it away.
