If you have your donate page active on your OTS show site, it will have the option for three set dollar amounts and one where a patron can add a custom amount.

Once an amount is selected "Donation Added!" will appear in the top left corner.

Click on the shopping cart in the upper right corner to see a summary of the donation.

Click Checkout, which is where the patron enters their credit card info.

Once the order is complete an email confirmation of their donation will be sent.
