I'm pleased to confirm that PayPal is back live as a payment option on this website. A minor "blip" meant that it was unavailable during the past week, but all has now been set right.
Please also remember that if you pay by any card (VISA, Mastercard, Debit Card or Amex), it may take a couple of days longer for me to process your order due to the length of time the card payment takes to come through.
