Paypal USA has always had a problem with vaping but (till now I guess) it was more the juice. You can use Paypal for e.g. fasttech and English juice orders. They've just always beenheads in the States. Basically sounds like Paypal was bought out because of that useless prat Icahn on the (EBay) BoD who probably just wants to kill it dead and appears to be succeeding from the little I've read so far.
Actually it looks like it's started to hit fasttech.
The 'paypal' button that used to appear at the checkout at fasttech has been replace by a 'bitcoin' button.
