I ordered a chair on Staples.ca, and it showed as "available". Actually it was out of stock. In order to let me place another order for a similiar product, they offered me a coupon for $25.
The coupon value was promptly refunded to my card and the chair that i bought was as good as the one before or better.
Great customer service, prompt replies to my queries and polite manner! It was such a pleasant experience! Thank you!
