Some okay prices on these cards as the British Pound continues to do well. Showing as 'Temporarily out of stock,' so an backorder, and hence will deliver as soon as stock become available. VAT is removed at checkout to bring the final price down.

EDIT: As pw2002au pointed out, Amazon only charges you when it delivers the item. If the pound recovers and Amazon hasn't shipped it yet, it's a good idea to cancel your order.
For back order items don't they wait to charge you till its in stock? There is a small risk of the pound recovering if so.
