Seat Covers

I am looking for about 200-220 seat covers for a reasonable price(around $1.90 each plus shipping or less) for july 7, 2007. From what I can tell ordering to rent online seems the best way but I can not find the right one. I found one online that was $1.90 each plus shipping. I wanted to look at other options and I can not find any..so I am looking for suggestions. Thanks for your help.
