People keep saying things like this and I don't understand why the concept is so hard to figure out...I really don't know what is going on with PayPal. I do know that yesterday I placed an order with LiteCigs and today I placed an order with Janty....all through Paypal with absolutely no problem.
The reason you can order through any particular supplier with "no problem" is because PayPal just hasn't gotten to that particular supplier yet. They have no way to "blanket ban" all ecig suppliers at once. They have to check into each supplier suspected of selling the products they are targeting and then manually shut that supplier down. This will be a drawn out process, one or two a day, until they get them all which I am sure is agonizing for suppliers who currently only take payments through PayPal.
So, you may very well be able to order from a supplier with "no problems" right now then you could check their website in an hour and find a notice that their ability to accept PayPal payments had been shut down (like is now showing on several supplier's sites)... it happens that fast.
