I was running this on a test site to give it a try in a comparison of other plugins of similar nature.
I installed easily and opened the configuration pages, turned on paypal to try how it looks and I was instantly pushed to purchase a 200 dollar tool to make that work.
Uninstalled and moved on.
I can not say this tool did anything, I did not give it a chance. I do feel though you should get a heads up on such a steep price for advanced features.
Not for me.
