Ok, so I chose the most complicated first website to try out.

1.) 10% of sales goes towards a donation option - but I want my radio buttons to default on a choice, so the customer can't 'add to cart' unless something is selected.

I know theres something I'm overlooking...

2.) Also, is there a way that the shopping cart can show the exact amount thats being donated?

One more thing:
3.) Is there a way that the shopping cart can 'suggest items' to upsell?


the website is http://starssignatures.com/pink

Thanks for your help!
