$25 · Queen quilted waterproof mattress protector - new

Queen quilted cotton top mattress protector, polyester waterproof bottom with polyester fiber fill. Fits to 17" depth. Just bought at Quilt, etc, thinking it was totally cotton. So it has never been used but was unpacked, that is how I discovered that it was not all cotton. The store will not take it back as it was on sale. Was on sale for $33, asking $25
