$550 Canadian!! what's that like $20 bucks american? LOL!! Just kiding confused, it all depends I would try to work it out with you instructor tell him you just don't have that right now and see if you can't make payments or something perhaps even if your son could help out around the Do-Jang and work a bit of it off. I don't know many instructors that wouldn't consider doing something to help ease the burden. It doesn't hurt to ask.
