NEW VIDEO “Joanna & Pup Play

Purchasing via Paypal

Some customers are having trouble buying our videos.  It depends on which bank issues your credit card.  Here’s the situation as we understand it.  It’s your bank which is declining your card to PayPal.  The bank tells PayPal that they don’t recognise your card or that it suspects some fraud on your card and declines payment.

They only do it with erotica purchases.  We think the banks only want people buying erotica from sites that they supply gateway services for, not PayPal.  Your bank will let you buy other things from PayPal on their credit card but not erotica.

You can get around it by linking a bank account directly to PayPal. Then you choose that as your principal payment method on PayPal settings for the purchase from Mercury and Diamond.  Then you can set it back to credit card after.

The name of our business as it appears on customer card statements: MERCURY604

Our Background

 Joanna was a university professor and Blaise a successful business owner for many years before they met, in unusual circumstances, in Sydney, Australia and formed a firm friendship.  After beginning their internet career with “Mature Beauty Tips” which had resounding success for a number of years, they shifted their focus to sex commentary, where they felt a new understanding and approach would be most valuable and useful.
