This one's for GtrsRGr8, who was disappointed in missing out on the 99p cookbook sale over at Amazon UK. I just noticed that some of the publishers appear to have the same ebooks on sale for 99 cents, which is even cheaper than 99p!
Mitchell Beazley at Amazon US and
Mitchell Beazley at Kobo US
Weidenfeld & Nicolson at Kobo US
Hodder & Stoughton at Kobo US
Kyle Books at Kobo US
It may be that all of these publisher have the same books on sale at Amazon, but I had difficulty coming up with queries that found any of their books.
