Add-on: Prompt special offer on checkout


I am looking for an add-on which will show a selected product on the checkout page. A kind of “[color=#ff0000]Hey, have you seen this great offer - lets add it to the shopping cart[/color]”-function.

The offer should be a product from the catalog, which has been selected in the admin part.

I have not decided yet if it should be integrated on the checkout page or prompt.

Does anybody know if this been developed?

Have you tried cs-cart block system?

I have not worked with CS-Cart so long yet, so I am not that much into the options with blocks.

But I will look into it.
