Excellent customer service I somehow ordered the wrong size. When I called to return them they told me to donate them to habitat for humanity or wherever I chose to donate them and sent me the correct size with no charge. Thank you; and yes I donated them to habitat for humanity.

I was under the impression that I was to get a 20-25% discount on this purchase, however, l received neither. That discount is really the only reason I made this purchase. Your information was confusing. I am disappointed to say the least.
