Nashbar usually has deals on their branded bars for less than $20. Be it risers, drops or bullhorns. I got a set of risers from them for my wife and they were nice quality. Coupon codes are posted on their site often as well if they are not on sale.

If you're around campus I'd maybe check out some LBS's in the area. If they are closeby they probably have a shop or two that caters to SS/FG and may have some deals close to what you'd find online. I was about to pull the trigger on a BD bike for my first FG as well but went by the shop here and ended up with a bike for about what I would pay online. Got a fit I needed and it came with a warranty and service that you won't find from an online shop.

Another good idea that may be an option for you would be to see if their are any local bike co-ops by your campus. Usually with those by donating time you earn the option of purchasing a used bike their for either free or a very minimal cost. I didn't know about the local one here before I bought my bike but I wanted to learn more about it so I started donating my time. I went there with absolutely no knowledge at all (I could change a tube thats about it) but after just a few weeks I had built up a nice mixte for my wife from just parts around the shop. I bought some new items from there (tubes, tires, brake pads) and I think total cost for a pretty nice ride was less than $30.
