Check Craigslist. I picked up 11 sets of flash cards for $75 and a million supplements (literally everything I could need 1L year, plus a couple of 2L ones) for about $5 each. I was also able to introduce myself to two practicing attorneys in my area, which will be invaluable in the future, especially since one of them has offered to act as a mentor to me throughout LS and beyond. The only thing I've been told to buy new is the Glannon CivPro E&E, since the FRCP changed in 2007 and the sixth edition uses the new rules. Casebooks can be found on Craigslist, too--I picked up the full Chemerinsky casebook as well as his hornbook for just $10 total.
