I've never heard of it but I have a few comments and caveats.
Generally, with the exception of its own site and a few major retailers, Coach doesn't authorize websites to sell its products. They don't allow boutiques or even individuals to purchase their items in bulk and in fact, there are numerous posts on tPF from members here who have been banned from Coach when suspected of being resellers.
Therefore, it's always a good idea to ask about sites or sellers who seemingly have an endless supply of high quantities of Coach items.
According to the "about us" section of that site, it states that they buy from the US for resale in Malaysia. There are some US sellers who have regular customers in Malaysia for whom they purchase Coach and ship.
But whether this website buys from a trusted source, I don't know. And there's know way to know whether they even have the product (in stock) or if they sell authentic items because the pictures they use are Coach's stock photos and don't show the actual items.
I'd ask a lot of specific questions as to who they buy from in the US and also ask for actual pictures.
