This particular field has been set to work with the radio button product above.Option fieldFirst Option $2Second Option $4Third Option $6Use this field to add options to a particular product. I am associating these options with the drop down product above.A special note for all these fields - you must add the price with the label, otherwise the price will not show next to the product.Shipping field options For this field, you have the option of offering a single price (or flat rate) shipping. I guess you could also use it to confirm that you have free shipping by leaving the price at $0. The other options are drop down or radio buttons, but this assumes that there will be one shipping price per method, so no additional shipping charges will be calculated by adding additional quantities or options.Total $0.00 Enter your email if you want this form submission to be sent to you.
