LOOKING FOR CHAIR COVERS!

I`m having trouble finding chair covers that I can afford!
My reception is in Lady Lake, Florida that the Harbor Hills Country Club. I`ve seen a lot of advertisements for chair covers at $2.00 each, but then when I call the companies, they`re really charging around $7.00 per cover! I can`t afford that! Does anyone know of a place that provides AFFORDABLE chair covers in my area?
