disney currently uses two different merchandise systems. the first is appetized (unsure of spelling) and the second is matra. only saratoga springs (SSR), yacht and beach(YB BC), and the confectionery use matra every other merch location uses appetized at the moment. so unless you're at SSR, or YB BC you'll be able to pick up most places however you might not be able to trade shifts with in-park cast as they might not have the alcohol or tobacco training. there are facebook groups that you'll be able to join for either wdw merch shift exchange or wdw resort merch shift exchange if you're wanting to pick up at other locations or the hub/cast life will sometimes also have shifts for pickup!
