It's bad enough that their website will often fail when you try to sign in, add an ebook to your cart, view your cart, or complete the order (often requiring one to hit the back button a dozen times or more). Last year they removed the option to download your ebooks to your PC from the website, even the ones that are supposed to be DRM-free. Last summer they removed the ability to read your ebooks from the website.
A few days ago, they changed the website so that it no longer tells you that you're trying to repurchase an ebook (at least if you have one click shopping turned off). Now it lets you go through the entire purchase process, and then a few minutes later, you get an email, or two, or whatever, telling that the order for the ebook was cancelled because it was out of stock, but the rest of your order will be shipped, unless you get more emails telling you that they, too, are cancelled because they are out of stock.
I wonder what unbelievably stupid thing they'll do next? I have no hope that they'll actually fix any of the things that are broken. I doubt they'll even fix the email text to say that the ebook purchase was cancelled because I've already purchased it.
