Hello Wade and thanks for your generous feedback
The suppliers in the directory have undergone a full verification approval process, that process includes many things, but it does not include any price related measurement. Because of the verification process our suppliers have passed, we have full confidence in recommending them to our members as safe to trade with.
Things like researching price and other account differences between suppliers is down to the member to choose the best option for themselves.
Remember that there is a difference between wholesalers and dropshippers. While it is becoming more common for dropship suppliers to require tax id to establish accounts, there are still some that do not. However, wholesalers will always require a tax id for accounts for taxation purposes.
