ok, then you can get 10% off at some stores (notably World of Disney at DTD), also there are dining discounts, but you won't need those. You can also save on some tours and sometimes on Cirque de Soleil.
There are special Pins (the actual metal ones, not discount codes!) just for Passholders. If you enjoy adult beverages you might consider getting the DDE card since it gives you 20% off beverages as well as food so that could work for you. And there are special events just for Passholders too, like getting in to see the Haunted Mansion early after it's rehab!
