Well it?s simple really. The end user (you?re surfer) joins one site, and is given trial access to another increasing revenues TREMENDOUSLY! This can be done between your own sites, or you can cross sell to other WTS merchants.
So you might be thinking... "Ben, this is an untapped vain! How do I cash in?".
Simple! ;-)))
If you're currently a client with us, drop you're merchant support manager a line and we'll flip the switch upon your request!
If you're not WTS merchant, it's time to become one!
Feel free to contact me with any questions you may have, or simply fill out our online application at

Current WTS merchants, please feel free to use this thread as a gateway to arrange any cross sale deals amongst yourselves.
