If you or someone you know still doesn't own a Kindle, today's a great day to fix that. Amazon has taken $20 off both of their E-ink models, dropping them firmly into impulse buy territory.

The flagship Paperwhite will only set you back $99 today, representing a very rare discount, but if a backlight and touchscreen aren't worth much to you, Amazon will sell you the older model for just $49 today as well. Even before this promotion, the Kindle was really the only E-reader worth considering, so take advantage of the savings while you can. [Amazon]
