Setting the 3rd ticket as free if user purchased 2 tickets

I have an event taking place over 3 days. We are running a promotion where you purchase 2 days, you get the 3rd free. There are adult tickets (15+) for $15, Youth (5+) for $4 and Child (4 and under) free. I need them to be able to select ticket quantities for their desired days with logic built in that if they purchase tickets for 2 days, the 3rd is free. I currently have 2 form I am working on. But I'm running into multiple issues. One being that I can not set the default ticket quantity to 0.

Hi LadyHillWinery,

Thanks for reaching out to Jotform Support. You can enable Special Pricing Per Quantity, so when they select 3 days, the price would still be 30. Here's how to do that:

1. In Form Builder, click on the Wand icon on the right of the product list and on the right panel that shows, click on the Pencil icon of the product.
2. Under the Options tab, click on the Pencil icon of the Quantity and enable the Special Pricing Per Quantity option.
3. Make sure the Range is set to 0 -> 3 since the event is only 3 days and enter the price for each day option.
4. Now, just click on Save Quantity, and that's it.

Here's a sample result:
