I've had a problem using my mastercard last week to make an order with a supplier and they wouldnt do the transaction
through paypal, so I had to link my bank acount with paypal to make the transaction go through, I called paypal and they told me it was there inside security that wouldnt let it go through, called my credit card company and they said it wasnt them, I think PAYPAL has had an issue or two with people either returning e-cig stuff or they might be having a problem with e-cig stuff in general using a credit card for some reason, like I said once I linked my bank account it was fine, I belive paypal gets paid right away through the bank and theres not the recourse there is with credit cards for paypal, Just my 2 cents and thoughts
