That's probably the worst reasoning I've ever heard. Income is income, and depending on the laws of your local jurisdiction, you're supposed to pay taxes on that income. If you have bitcoins, and you keep them as bitcoins, it would be just like having a pile of Euro's or pounds laying around. If you convert those back to dollars at a higher exchange rate than what you paid for them, that counts as some form of capital gains.

The argument that 'it's hard to trace, so you don't have to pay taxes on it' is the exact same argument you can make for if you get paid in cash for something. You're still *supposed* to pay taxes, and just because it's in BTC doesn't some how make it 'special.'

It turns out I was mistaken (i'm really surprised they don't offer that). You might be able to do it by basically scraping their website, but certainly not terribly conveniently.

It looks like bestbuy lets some people do it: http://bbyopen.com/documentation/commerce-api (although you need to contact them to set it up). I might take a look for sites that do offer an API for automating purchasing.

Amazon.com has an API that lets you make purchases and things. How difficult would it be to basically glue one of the bitcoin exchanges to amazon's API so that you could automate the currency exchange? Assuming someone had an account with a currency exchange place, it would go something like this:

1. A firefox plugin or similar adds a "Buy with BTC" button to every amazon page
2. User clicks 'buy with btc' button for an item, and is taken to the btc2amazon.com site.
3. User sends btc2amazon the appropriate amount, as well as providing shipping details
4. btc2amazon waits for transaction to clear, then makes purchase via amazon with provided shipping details.

Basically what coincard does, but just make a plugin (like a greasemonkey script) that integrates it with all of Amazon.com . . . thoughts?
