all of the above plus discounts on hotel/motel rooms, free barclay's checks (like traveler's checks, only a different company), money exchange (from usd to something else - you have to give them a heads up). we've also used them as travel agents. depending on the staff, they may or may not be the best at that.
we always get the trip tix. we never buy their products, like money belts or those things. they're grossly overpriced.
