You might have noticed that the price of my SR-71 book on Amazon is highly variable. It was originally something like $13 direct from Amazon; it’s now something like $27 from secondary sellers on Amazon. This is due to Amazons supply having sold out. I’ve been informed that another shipment has been sent to Amazons supplier, so the direct Amazon price should return to normal in three weeks or so. Just in time for Christmas, so when that price returns to normal don’t waste a second and promptly order a few hundred copies.
It remains available direct from the publisher for £8.99 which is about the price it should be on Amazon… but shipping from Britain to the US is kinda steep.
