Clearly, Amazon isn't about to start accepting Bitcoin anytime soon.  This proposal outlines how a userscript could basically fully integrate Bitcoin into Amazon, whether they like it or not. 

For the developer's convenience, the proposal outline is so specific that all a developer has to do to fill this need is blindly and brainlessly code up a userscript.  I'm too lazy at the moment, but someone's probably going to code this up.

Now, you ask, what are the benefits?  One can already buy products on Amazon with Bitcoin. 
However, from the technically-challenged end users' viewpoint, a familiar interface is infinitely better than another site.  Also, integration is good for everyone... nobody likes having two tabs open when one would do, or ordering a gift code, waiting for it, and then finally receiving it and using it to buy things.

Requirements:

1. Service for placing Amazon orders via Bitcoin.  This must accept API calls for the following:
> Create new order with selected items and shipping/billing address
> Get new address for an order
> Get current price of one bitcoin
The service must also be able to detect if the appropriate amount has been paid to the address, upon which someone (bot or user) is notified and orders the product.
2. Cloud wallet API
3. Transaction radar websocket API

Actions taken on all pages: BTC / USD / Both options for price display.  Replaces all prices with the appropriate amounts using the Amazon service's determined price (whatever it is).
Actions taken during checkout: Add "Pay with Bitcoin" to the payment options.  This does not open a new page, but overwrites the current one.
New Bitcoin checkout page:
Displays payment address, final payment amount, deadline for payment and a QR code just for kicks, and also submits a request to the backend to create a new pending order. 
Opens a websocket connection to some transaction radar API, and listens for your payment, while displaying a scrolling address bar. 
A confirmation popup then appears, saying that you need to pay X bitcoins to address Y, and asking whether you authorize the transaction.  If you click OK, it executes the transaction with the cloud wallet.  (Alternatively, we could use a local Bitcoin client with RPC, but this is not necessary because of the demographic we're targeting.)
When you are done paying, the page hides the scrolling address bar and tells you that you're done, but that the order needs to confirm. 
While you go get a coffee, another scrolling address bar appears. 
When X confirmations have been detected by the transaction radar, the page displays a success message.  Big green check mark included.
To be clear, the backend does its own confirmation, and does not rely on the userscript for confirmation. (Of course!) 
This page must conform to Amazon UI standards and look exactly like an Amazon page.

This is probably not the most secure userscript (I don't know much about security).  However, I'm just throwing the idea out there, and maybe one of you can make it usable, intuitive and secure.

Is this a stupid idea?  If not, can it be made secure?  If not, are there any other problems with this implementation?

If this can work, one of you can code it up in 10 minutes and we can have a new marketing tool.

The interesting part is that there is a place to enter a gift card on the final order page, AND it's AJAX. That would make it really easy to have the script wait for the gift card code from the server, submit the gift card code, and then submit the order.

Cool idea!  Here's a stab at replacing the prices, with a hardcoded exchange rate.  Hover to see original price.  Tested in Chrome and Firefox, it seems to get most prices; I've noticed some that get loaded after the page has loaded don't get replaced.  I'm not sure the best way to handle that.  It's only USD right now.

Code:
// ==UserScript==
// @name           Amazon Bitcoins
// @namespace      joeyhewitt
// @description    Show prices on Amazon in Bitcoin
// @match          http://www.amazon.com/*
// @match          https://www.amazon.com/*
// ==/UserScript==

// https://gist.github.com/437513

(function(callback) {
    var script = document.createElement("script");
    script.textContent = "(" + callback.toString() + ")(jQuery);";
    document.body.appendChild(script);
})(function($) {

    var BTCPerUSD = 6.59;
    var convertUSD = function(text) {
        return text.replace(/\$\d+(\.\d\d)?/g, function(USD) {
            return (parseFloat(USD.substring(1)) / BTCPerUSD).toFixed(2)+ ' BTC';
        });
    };

    $('.t14, .price, .priceLarge, .listprice, .tmm_olpLinks>a, #actualPriceExtraMessaging, .fionaBuyBox font, .t11, .mbcPriceCell, .plusShippingText').each(function() {
        var $priceEl = $(this);
        var originalPriceText = $priceEl.text();
        var btcPriceText = convertUSD(originalPriceText);
        $priceEl.hover( function() { $(this).text(originalPriceText); },
                        function() { $(this).text(btcPriceText) } );
        $priceEl.text(btcPriceText);
    });

});
click to install

As for the actual purchasing part, http://spendbitcoins.com/ takes BTC and gives Amazon gift codes in several currencies.  If they could provide an AJAXable API for price quotes and retrieving the code (including updates on them waiting for confirmations, etc.), we'd be mostly done, right?

EDIT: Updated code and link

Hmm, that's another way to do it... we have two approaches then, essentially:
(1) Pay for the order in BTC, and don't actually complete the order.  Hand the order to the Bitcoin Amazon service and have it complete the order (whether through a human operator or by bot)
(2) Pay for the order in BTC, get an equivalent gift card code, and use that to complete the order instantly.

I do like the second one more.

I recon this approach would work for any site or B&M that accepts their gift card. Let's say I want to go to dinner tonight at Applebees and want to use my re-loadable gift card which is low on funds at the moment. I could top it off via Bitcoin with your approach. Genius!

Oh wow, you're right.  This approach to Bitcoin integration actually has far-reaching implications.
We should probably get it working ASAP and have it mentioned on lovebitcoins.org.

I replied in the newbie area, but Maged has moved my post here, and I assume it was he that whitelisted me. (Thanks!)

I wasn't sure if anyone noticed the moved post, so if you haven't, check out my userscript for replacing the prices (hardcoded exchange rate right now) and let me know how to improve it.  I've also asked Jeremy West of spendbitcoins.com about an API to help us do the purchasing.

It would be awesome to get lots of gift cards working like this!  spendbitcoins.com might help in that respect; they've got several already.

We're actually working on something very similar... for a lot more than just Amazon.

When you're done with Amazon, do The Popcorn Factory gift card, since popcorn was the first purchase from a vending machine retrofitted to accept Bitcoin. Then follow that up with the 100's of other gift card accepting companies. That should keep you busy for the rest of the year.
