I purchase couple watch from 100bestbuy.com and pay online and got that product within 5 days through courier but when i received the product i saw that the watch do not works properly, then i call 100bestbuy customer care and they told me to return the product to our address and after receiving the product we will send you new one . Then i courier the product to their address and after 10 days i got my replace product. This time the product is really awesome and original, the site facilities are good as well as their delivery. If you have any problem, you can call to customer care. I think they will help you.
