Most worth it XF addon ever!
I've been using it for over 2 months and this addon is just awesome.
It boosted my sales, easy to config, work fine with PayPal.
And it made me discover the "Guest Payment" (pay before register).
And the cherry on cake, this have eradicated the spam registration on my forum.
So, I can only recommend this addon, great result!
Yes, maybe it's a little expensive with the branding removal, but it's quickly profitable.
