I need a simple ajax "Add To Cart" script for a Magento store.
Basically this is how I see it working the easiest. I need something that will use jQuery to (when a "Buy Now" button is clicked) update the text in the shopping cart (add the item being bought to it), then store the data and then on the next page refresh actually add the item to the cart.
I'm open to any ideas, I just want the files to all be in the template and skin folders, not the core folders.
I found a tutorial here, but I'm more of a designer than coder so haven't managed to get it going, but it might be a good place to start:

NOTE: If you are interested, please outline what experience you have with Magento. It's far from the easiest platform to develop for, so I'd much rather you just told me what you've done with Magento (preferably with some links) than send me a big copy/paste brief about your business, thanks!
