YOu can buy a nice vintage tenor for 750$ and spend 750$ whether on a drum set or a keyboard (you don't need to spend 1500$ on keyboard or a drum set neither of which is your main instrument)..
I bet that if you look enough on adds in your area you can get a vintage tenor for 500$ , used (or new) keyboards for 500$ and a used drum set for 500$...
The problem is it is a store credit, and must be spent in that store. Most stores can't order up used saxes, so new is probably his only option, which eliminates a Bari, and might eliminate a good keyboard as well. He could get something to learn on, but not a true pro keyboard.
The stores website is very poor, but it shows a partnership with a store that carries used drum kits. I'd use it up on quality used drums and GOOD used cymbals. Probably the best bang for the buck, and a reasonable resale to get money for a good sax in the future.
