Re: Pay Pal Add to cart button
These can be links to pages of your choice.
For example, if they cancel the order, you could just have the cancel url as your homepage? So they go back to the site again.
For succssful payments, take them to a page called 'thank_you' or similar and just create this new page with words like...
Thank you for your order, your goods should be with you in 7 days... blah blah blah... etc etc...
I also sent you an email, but you may not have received it. In your email link that I just got you to change to mailto: get rid of the www. bit, then your email will work.
Don't aim for success if you want it; just do what you love and believe in, and it will come naturally.
