The website is beautiful, but I don't even think the notion of a "javascript shopping cart" should exist. It's stupidly dangerous. This is real money we're talking about! Wow.

Also, this confused me for a few seconds...I thought dials went clockwise ;) http://i.imgur.com/QEl7v.png

It's not a big deal. Just do a check on the backend. You can swap price tags in stores too, and they most certainly will not honor it if they realize.

I've done a mid 5 figure number of transactions through PayPal for digital goods, and I don't use the encrypted links (mainly because Flash doesn't support them). There have been a remarkably small number of fraud attempts (<0.1%).

One guy bought a game for $0.01, then initiated a chargeback when it didn't arrive. I raised my eyebrows, issued a refund, and the matter was over.

Not being able to trust the client is intrinsic to JS shopping carts, but I don't think this is a critical flaw.

Although I don't see what prevents merging the JS cart with a web based cart on the checkout page. Send the contents, and the page with the big 'click to charge card' button is generated server side.

Actual transaction happens in Paypal's page. Not for a complete e-commerce site, but for simple usages with few products i beleive this is a good solution.
