Welcome to SaleHoo, yorryo :)
You have to remember that not all suppliers with good offers are good suppliers at all...I checked them out further and found a few more reasons why you should stay away from them -
1. They are relatively new - Their whois registration shows that they have been online only since May 9, 2011, barely 2 months old.
2. Their contact details are free email accounts. ideally legit suppliers will provide their customers with a working land line number, valid physical address and a domain based email address.
3. I could not find an information on the types of payments they accept. My guess would be that they're going to ask you to pay using wire transfer.
Hope this helps :)
