Every summer Smashwords has a ebooks promotion in July. Ebooks in the promotion can be free, discounted 75 percent, 50 percent, or 25 percent. Authors can put any or all of their ebooks into the promotion. The prices are only good with the coupon code and at Smashwords.
I don't think you need an account to get free ebooks in the promotion, but, if they're discounted ebooks, you have to have an account to pay for them.
Below are our contributions to the promotion. Remember, you MUST use the coupon code.
