I keep getting denied when I try to purchase Lindens In world. I use paypal, which in turn pulls from my bank account( or debit card) Suddenly I get denied. My last successful transaction was the 25th of Sept. Using Paylpal.. just as I always have. I thought perhaps I should add the Debit card(VIsa) to my billing page, and am unable to do it. Reluctantly, I had to use another currency site to purchase Lindens, and I would rather use the Linden exchange.. if it would work.
