You're probably going to be dealing with a LOT of street dated shit over there depending on what area you're specifically going to be in (ex: DVDs, video games, collectable toys). if you run into something on your label strip that's street dated, put the label from the previous product over it until the real thing is supposed to be out.
If you're doing revisions, that usually is changing labels and moving stuff around with maybe a few new things being pulled.
