Hi Aqeel
Just two quick points to follow up on what information Rachel has given you.
1. don't expect to buy genuine designer brands, anything branded like that will be fake
2. If you are going to do business with them, stick to a safe payment method only, credit card or paypal, no money transfers
I'm not saying they aren't trustworthy, it's just good standard practice when dealing with a Chinese supplier.
Cheers
