We have just begun a route with 4 drink and 3 snack machines in 4 bldgs with about 50-70 people per building. We have been servicing them for about 3 weeks and have some of the chips expiring soon. Just wondering what the usual amount of expired products we could expect. As we are still fine tuning the product line some chips and snacks aren't moving well even when we move them from one building to another. Any advice on this?
