Deja vu?
For those of us who have been around a while, we might remember this as being PayPal's original purpose in life. I remember paying back friends for lunch using PayPal and feeling like we were living in the future.
Only later did PayPal move into the merchant space more seriously. Maybe my memory is poor and they launched with merchants at the same time but it took a few years for me to ever purchase anything with PayPal, it was all between consumers before.
So ya, welcome back PayPal?
