Sam's Club review: Snacks expiration date

I visit Sam's club once a month to buy groceries and school snacks for the kids. I noticed one of the snacks (Graham crackers) I bought just last month was already expired because I realized the taste was not right, even though my kids have been eating not knowing they were bad. The snack boxes usually come in large quantities (40 bags) which means you should at least enjoy eating from it for the next 30 days. Did not care as much but I figured I will always check expiration dates on my next visit. Sure enough I went in today to be surprised that many snacks will expire in February or March. I also found some already expired dated January (such as the Pringles chips small packs designed for kids to take to school)! This is a serious problem, especially snacks that mainly kids consume. Are nearly expired items always sold at Sam's club? Something that every parent deserves to know.
