I ordered 4 covers (2 in a package).  I received 1 package of 2 covers, and another package with only one cover, and a second smaller package with only 1 cover with one velcro strip sewn on the wrong side.
After several contacts with your representatives, I finally got credit for the one package, and later a sales rep ordered another package of 2 at a sales price.
All in all, I find it very difficult to work with Wayfair.
