Amazon has a problem when it comes to print-on-demand books, or at least it has that problem with print-on-demand books from Ingram Spark.
My MLVC60 book with Anthony Coombs just went on sale, but Amazon's link offers the above very deceptive result. From this result, it would appear my book is available, but at $89.80, not the list price of $75.
If you click in, you get another layer of deception. It still appears it's $89.80. But if you squint, you see there are new books at $75.
Finally, when you click on the $75 option, you get the actual book as sold by Amazon — and it is listed as temporarily out of stock. The message does say you can order it and will be notified when it's back in stock, but I can assure you most people have given up by now or ordered it for too much money from secondary sellers.
In reality, a print-on-demand book is never out of stock. But Amazon sticks to this silly message each and every holiday season with my books, and I invariably lose sales. Amazon has replied in the past that it has to do with Ingram Spark, and Ingram Spark has replied that it has to do with Amazon.
Bottom line, for you or anyone you know you would like to order: If you order at $75 directly from Amazon, it will be shipped relatively soon. Bank on it.
