How do I add an order bump to my checkout form?

1. Create the product for the bump first. Go to Payments, then Products, and create a new product with a name and a short description.
2. Set its price in the product's payment section. Whether the bump is one time or monthly is set on the product, not on the form. You can also show an original (crossed out) price.
3. Open your form and add that product as the order bump, replacing any product already in the bump slot.
4. Choose whether the bump is checked by default or off by default. Off by default is fine.
5. Choose the bump card style, for example with the price on the right side of the card, which tends to look better.

To change the bump's price, or switch it between monthly and one time, edit the product under Payments. It cannot be changed from inside the form.
