I see four titles on
Osprey Publishing's website that are marked down at the present time. They are all
$1.99 each.
Osprey is a publisher across the Pond (or if you're across the Pond, it's not across the Pond. ha), in Great Britain. They publish high-quality military and military-related titles. I don't think that I own one of their titles, yet, and I know that I haven't yet read one. But one thing that stands out to me is the cover illustrations often on, and in, Osprey Publishing's books--they are consistently
excellent.
Here are the titles and authors of the markdowns, followed by the retail/regular selling prices:
Napoleon Bonaparte, by Gregory Fremont-Barnes. $9.95.
The Russian Civil War 1918-22, by David Bullock. $15.95.
Panther vs Sherman, by Steven J. Zaloga. $15.95.
Roman Centurions 753-31 BC., by Raffaele D"Amato. $13.95.
Curtiss P-40 – Snub-nosed Kittyhawks and Warhawks, by Carl Molesworth. $15.95.
As you can see, the discounts from the retail/regular price are really steep! I'd like to buy all of those books, but my "must-buy" is the Roman centurions one.
The books are available in "multiple formats," which as far as these ebooks are concerned, at least, are ePub and pdf.
Here is the link to
the webpage with all five of the marked-down ebooks.
UPDATE: Osprey will direct you to place these titles into their shopping cart and purchase from them. However, I just found out that all of the above books are available at Amazon (Kindle mobi) for the same price of $1.99 each. If you want the ePub it might be easier just to purchase it from Osprey, even if you can find it for the same price elsewhere; if you want the pdf, it may be impossible to get it anywhere else, much less at the same price, and even if you can it almost certainly will be easier just to purchase it while you're there at Osprey's website.
