I'm unable to find Hot-sales-outlet.com's physical address (it wasn't on their website) so I can't tell if they're China based or not but with those prices, they may very well be. Their HermÃ¨s Birkin bag, for example, only costs around $200, when the real thing may cost between $9,000 to $150,000! I checked their website registration, and it says that their website was registered in San Diego on Nov 25, 2010.
I wouldn't recommend them personally. Number 1, the prices of their products are just too cheap to be authentic, plus, they're new (only 4 months online). Generally, you'd want to deal with suppliers who have been online at least a couple of years. Of course, this is not a guaranteed way of telling whether a supplier is good or bad, but genuine suppliers have usually been around for longer than 4 months.
