I bought from these people before and they are very good to work with. Often with free shipping.

I found one a couple weeks ago like the sewEzi table that has the set in machine style top for eighteen dollars! I was dropping off some boxes to the assistance league thrift shop , and just happened upon it. I like donating to them because they have a food pantry for locals.
My other suggestion is to contact the local quilt guilds that have surplus donations for the quilt shows. They sometimes have to store the left over items until next year and might have something you could buy.
