I'm curious to know why the 7 day EPC fluxuates sometimes when I don't have any sales. Today for instance it just shot up from 82.18 to 107.98 but I haven't had a sale at all today.

I've noticed this many times over the past year or two on days when I didn't get a sale, but thought maybe it was a sign that a sale was comming through or something of that sort.

Just curious if this happens to everyone, and if so what could be the cause?

One would assume you need a sale to make your EPC go up...
