Upsell & Cross Sell by SSC

**Update** - I've updated the review from 2 stars to 4. I can't give a 5 yet, as I really haven't had time to see results. I was contacted almost immediately after I posted my original review, and the issue was resolved.

I installed the app last week. I have added them as a user to finish the code install(s). I am almost through my free trial period, and haven't even been able to use it. Actually, it may be ready, but I have received no communication since the request to add them. I have no idea what is going on, and I'm pretty dissatisfied with their customer service/response.

Hopefully, I can update this review soon.
