I was going to suggest PayPal as well. Just a few short years ago, people would have scoffed. But I'm seeing more and more "professional" websites using PayPal.

This is partly because PayPal no longer requires your customers to have a PayPal account just to make a credit card payment.

And they do have free shopping carts. Though the free version isn't fully integrated into your website / domain, it does have the feature to have your customers click a link to return back to your website (the URL that you designate) once the payment has been made.

But if PayPal isn't your thing, a Google search of "paypal alternative" can dig up other similar free systems, some of them charging a fee something comparable to PayPal's processing fees, which are currently 1.9% to 2.9% + $0.30 USD.
