OEConnection Enrollment

Good morning.
We are a midsize dealer. Our parts manager quit and now they dumped it on me.
We've been using OEConnection for a while. And we just saw GM invoice that there are 3 OEC bill.
EPClink, Virtual Performance Coaching and RepairLink. What is the virtual performance coaching and if it's worth to keep RepairLink when we only have two garages using us? I know EPClink used for dealer locator and not sure about the Virtual PC. It kind of wasted spending over $500 and not really do anything for dealer.
Any input would appreciate it.
