On the checkout form, I think that you should have the zip code field prefill the city, state, and country fields. Or explicitly limit to US only. I think that people will wonder why you're not asking for their full address, most people don't know you can get city and state data from their zip.
The enlarged radio buttons don't look good on Firefox 7 Mac. In general radio/list/select fields not not scale well.
The 3% fund from you is a nice touch.
There needs to be a link which you can share with other people to help fund your purchase on the account page. Don't see a link.
Thanks for the feed back.
http://i.crowdfunded.it/apple-ipod-shuffle-2-gb-silver is the page people use to pitch in. you can click the fb like, google +1 or tweet to share with others so that they can pitch in.
Trust is definitely important here. How do you suggest I improve on that?
You need to redirect people to HTTPS, and your credit card form should have a secure lock icon as well as icons for the credit cards you accept. You should have a little promise on your form like "Your credit card information is encrypted for your protection by Industry-Grade 256bit Encryption and will never be shared."
As far as the rest of your website, for me personally, I trust websites that are polished, simple, and have professional copy. I was really impressed with Swipe.com recently and immediately trusted them.
Shouldn't that page say to whom I am giving money?
I think it's a nice concept. People will perhaps be more inclined to give if there was some sort of feedback mechanism. Something that will tell a complete stranger that the guy who was an ipod shuffle for his birthday deserves my $5. Perhaps if I knew that this guy gave $10 to someone else last week for a school textbook? Just thinking out loud.
