Lots of Self-Referred Traffic?

[MaxCPR]

I see a ton of traffic that seems to be referred from our own site. This matches up in 3dcart and Analytics as well. I kind of assumed it was some page on the website that didn't have tracking but I can't seem to find it. I noticed the self-referred traffic had a lot more visit value, so this might be an issue with the checkout flow, but every path I take seems to lead through pages that use the frame -- which has the tracking code. Does anyone else experience this?

Hmmm.. are you using the free SSL (store.3dcartstores.com) in the checkout?

Nope. No domain changing anywhere.
