Weddingbee boards

My whole wedding budget is 8,000. From what I can tell I'm getting a "good deal" on linens, chairs and tables (100 person event) and its coming out to 1,018.40. I can't seem to find a rental place cheaper and I'm getting these deals through my caterer. Anyway I don't want 1/8 of my budget going to these items.... any idea how to get cheaper tables/chairs??? My venue is a dance studio so they don't have anything like that. I'm trying to think if I could borrow this stuff from somewhere... people have cheap weddings there has to be a way to cut this cost down.

I think I can get the linens on ebay and craigslist cheaper and then sell them after.. but I don't know what to do about the tables/chairs
