How to contact suppliers?

Hi, im new to this. Just wondering, do I always have to fill out a contract with the suppliers? And, I see that some require creditcard information to bi filled into the contract, why and is it safe?

Hi Carl

Yes, you have to contact any suppliers you wish to discuss further questions or open an account with personally, but please use the contact information displayed in the directory listing to contact them.

In regards to paying them money, all our suppliers have been fully verified and registered in our directory as completely safe to deal with.

Cheers
