Why do Many Companies not print Expiration Dates on their Products?

A lot of products have codes, which are usually a mix of letters and numbers. Sometimes that's the manufacture date, and sometimes it's the expiration date, but the average consumer cannot decipher these codes.

My guess is that these companies don't want retailers to take their product off the shelves.

I just called Monster to decipher the code on one of their drinks. They told me that their drinks never expire!



How is that possible?
