Be VERY careful with this - it may end up hurting the charities you want to help. If Amazon dislikes this they may not be able to do anything to you (or to get you to stop it) but they may be able to shut down charities that are receiving money because of you. I wouldn't be at all surprised to find language in the affiliate agreements that bars this kind of thing and kills accounts of charities that use it.

I've made a few comments but you're at the top currently so I'll piggy back:

To OP, in the words of Hank Williams "I've been down that road before..."

I wrote a FF extension for our site that did something (I'm guessing similar), look at the site, and do the appropriate redirect with some ids and what not so i could track the charity for CJ/LinkShare/Amazon/whatever flavor. Theicon would turn green if you were affiliate shopping and I was taking redirects from Slickdeals and sites like it and making them my own transparently. You may have a newer, better method that gets around agreements sites make but from my experience, the affiliate houses (and retailers) much prefer actual driven traffic to a scraper like mine (and maybe yours). In retrospect, I can see that it was essentially a leach. I wasn't really encouraging many people to do shopping they otherwise wouldn't have done (well that would be the retailers point I guess). If I had any influence it was only marginal and I was taking revenue directly from direct traffic sites which, most likely, weren't happy and might not continue to drive traffic to certain retailers if commissions went down by a noticeable margin (or link jacking was allowed in the TOS).

I haven't read your code, I'm purely guessing as to what it does, so if I'm offbase let me know and I'd be very interested in your approach).

EDIT: After finishing that novel, I actually looked at the site. Does it just redirect any link to Amazon? I was expecting some link-jacking and ID insertion, so maybe nevermind. Mine was charity based as well (similar to Goodshop) but a bit more aggressive (in the charity's favor) which is where I believe the downfall to be.

Still I think @atwebb is right and as http://socialvest.us and http://aflattr.com were already shutdown Amazon is just not that happy with someone taking their revenue to charities. If it's just redirecting to smile.amazon.com it could be alright as it's the "sane" revenue share of only 0.5% and Amazon is promoting it itself, but still the automatic redirect will perhaps let them kill it.
