put your ideas for kindle 2.0 here

All too often, you buy an item or two and realize you're only a couple of bucks short of getting the free Super Saver shipping. The cost of shipping is generally more than the cost difference, so you add some small item you don't really need just to put you over the top. Heck, there are websites dedicated to just this process (http://www.filleritem.com/ for one).

Instead of having customers buy these ridiculous little items that they don't really need and will likely be thrown out anyway, how about allowing customers make a charitable donation in that amount to put them over the free shipping limit? They don't buy something they don't need, Amazon doesn't have to ship anything extra, and money goes to a good cause. Everybody wins.

Amazon is all about automating the heck out of things. How 'bout letting me know that the USPS tried to deliver a package to me and that it's been a long time and I should follow up. E.g. placed several orders at amazon; just noticed one order never arrived; it's been a month. Amazon and USPS websites report it's still Status: In transit.
Never received the USPS delivery attempt notice. Hopefully the USPS hasn't shipped it back.

Related: USPS doesn't give me a way to request they try again online.

the kindle looks like a great product. get the user experience right, and launch that thing. can't wait to start saving a bunch of trees by getting my books, magazines, and newspapers on it.
