One of the many reasons I started stockpiling a year ago and am now just picking up a few odds and ends now. Because those tobacco regulations also include not being able to use a credit card to purchase tobacco products.
I remember way back when, I had a standing monthly order with one of the Indian tribes that sold online. Once a month, they would charge my cc and ship me 6 cartons of cigarettes. Around 2005-ish, that cc prohibition came into being and I had to switch to electronic check for payment.
So I assume once e-cigs are 'deemed' as tobacco, that cc restriction will fall on them too.
There may be some outs. For example, FastTech can't use paypal for certain items (but they can for most of their vaping items!). So, if you want to use paypal, you order something else that costs the same amount. Then cancel the order, and get an FT credit. Use that credit to buy the other item.
You get your vape gear, but as far as PP is concerned, you just bought a "Swedish Manhood Enlarger" (complete with manual).
Perhaps online vape shops should start enlarging their scope - Suppose every vaping item page showed a "People who bought this also bought" selection (at the same price as the vaping item).
Just thinkin' here...
