Would L.A Boxing give me a discount?

I'm eighteen years old and I recently had a trial week at an L.A Boxing near me. Though the individual attention wasn't amazing (i.e even as a well-informed amateur I could tell that improper leg positions weren't being corrected), it's an amazing workout and, I think, is a great way to get my stamina up for when I actually want to spar with someone. Also, the cles early in the morning are supposed to be a lot more in depth, with a lot of individual attention. Anyway, its $700+/year, and my parents put their foot (feet?) down. Actually, it wasn't the price- they just don't want to pay. After a lot of thinking (staying in shape v. having more money in my pocket) I have decided to pay my way myself. The payment is supposed to be full up front, but I was wondering if they'd give me some sort of student discount, and maybe let me pay them in two parts? Thanks!
