I was just trying to purchase “Pro Open Source Mail: Building an Enterprise Mail Solution” as an ebook from Apress. The price is quoted as $25 for the ebook but when I added it to my cart, I got a $34.99 charge. I looked at another book quoted at $20 for the ebook but when I added it to my cart, I got a $27.99 charge.
Hopefully they’ll fix the problem soon.
Update: I was told by Apress that the cart price was correct. It was the price on the website that was wrong.
