We make it very easy to add extras during checkout:
- Express processing
- DHL Go Green Plus
- Gift wrapping
- Promotional participation
We add a product, let's say “Express processing,” to your shop. This can be selected during checkout in addition to normal shipping. You can determine the price directly in the product itself. We simply place the product in a deactivated category, e.g., “internal.”
Under Configuration > Additional modules, you can choose which product should be displayed during checkout.
This changes the checkout process. Unfortunately, this cannot be made update-proof.
