How can I remove the shipping from one item in the Authorize.net payment form?

Hopefully this is my last question for this form. You have been a great help, thank you! Is there a way to not include shipping on a donation if the person only chooses to make a donation...or is there a way to add text next to the field indicating that if they wish to make a donation instead of purchasing a t-shirt to visit the Foundation's website? Thank you!

You can set Shipping per Product item instead of Flat shipping rate

Hope this helps.

If all items except for the donation require a flat shipment amount, how do I remove shipping just for the "Donation" section.

I'm sorry, but I don't think this is possible in the payment integration. A workaround would be to set up a donation form and put a link on it in the item purchase form. The person can then click on that link if he or she wish to make a donation instead.

Or, embed the donation form to your website and place an instruction in the item purchase form.
