When I was checking my Paypal.com link I found this great announcement. Things really may be taking off in a positive direction with the idea of people Stepping Up and Saying What Is Desired (in sync with the greater good not greed.)
I will get back to what I was looking into and realize that some purchases under 100 dollars are not eligible for the 6 months of interest free credit, oops! Best not to use that Paypal Credit for small purchases or donations.
Well hopefully some of the interest I paid (less than a hundred but still much more than I expected...) will go to the good causes.
