Hi ebilarun,
From their wesbite, I learned that wholesale2b.com is not a supplier but they provide a dropshippers/sources. Sorry but I haven't tried their services and I haven't seen any reviews about them online. Hopefully we hear from members who have used them.
As a SaleHoo member, you can access the directory to view a list of dropshippers. Let us know if you need help in this line. :)
