There are two great options available if you want to offer a discount to those who sign up and pay for an item. You have the option to offer a discount for people who sign up and pay early or you can offer discounts based on the quantity of items purchased.
Once you set up the payments feature on your account, you will be able to create a sign up as you normally would. When you get to Step 4: Slots, scroll down to the Advanced Settings and turn Collect Money on. When you enter a slot, you’ll have the option to select the “Pay $” checkbox and enter the discount details. You can also edit those details in the “Edit or Delete Your Slots” area on the same step once a slot is added.
