For those who have a Kindle Fire or use the Amazon App store, they're giving away $100 of apps, with the main one of interest being the Oxford Advanced Learner's Dictionary, which is usually $40. This dictionary speaks out the word of actual recordings in British or American accent for pronunciation.
It has a few others that may be of interest, such as WiFi file explorer, which allows the Kindle's file system to be browsed from a PC web browser to download/upload files without using a cable.
For those into anatomy, they're also giving away Essential Anatomy 3 which presents detailed graphics of the human body such as muscles, nerves, skeletal and son. This normally retails at $24.
To access the list, go to the Appstore on Amazon.com and this offer should appear in the right banner. The offer started yesterday and runs until the end of today (Friday 1st August).
