Hi and welcome to SaleHoo, tonebo :)
Crealle.com is a relatively new site. They have been online for only a few months (registration details through Whois shows the site was created last March 16,2011) so its difficulty to locate any feedback about their products and services.
They do accept safe payment methods, PayPal and Google Checkout.
Personally, I have not used them so I cannot vouch for their reliability as a supplier.
We do have suppliers in our directory that offer similar products to those on their site. If you are looking for anything specific please let us know, and we would be happy to do a search for you.
