This add-on has been invaluable. I use it to pay for referrals and I could not operate without it. I even have to wait to update just to make sure I do not loose it.
I'm giving it a 5 star because support has always been great for me and every issue I have had has been addressed.
I have a few feature requests in and I'm sure eventually I'll see them cause the team is that good.
Thank you for the great add-on and keep up the good work!!
