We have recently signed up for the buy button service with Channel Advisor. This is a great platform for people that offer products but don't sell direct to end user. We can now see how much traffic we are generating for our resellers. We are now using this data to help our resellers grow their business.
The service we have experienced so far has been great. From the first meeting to the launch date the team have been a real support and have worked with us so we get the best out of the service.
