Overview of the Configuration

Dollarlabs offers a multitude of discounting options and strategies. For the purposes of this guide, we'll focus on two highly requested discount styles that currently Shopify basic discounting does not support with Downpay:

• Discount only when paying in full
• Buy X Get Y

Discount only when paying in full

This section will cover how to offer a discount only when a customer pays in full.

Setup

1. Install Dollarlabs Ultimate Discounts from the Shopify App store and open the app in your Shopify admin
2. Create a new Product Discount
3. Choose Automatic, and name it something like 'Pay in full'
   
4. Under Discount 1: Select Percentage and choose whatever percentage you want to offer when paying in full. In this example we chose 25%
   
5. Under Condition 1: Select 'With Selling Plan', 'is', 'equal to', and 'false'. This ensures we're only looking for products that haven't had the deposit option selected.
   
6. Click AND
   
7. Under Condition 2: Select the product(s) or collection(s) you want to qualify for receiving the discounted price on. You can use any of 'Product Collection', 'Product ID', 'Product tag' or 'Variant ID'
   
8. Select the other options as applicable. For full details on those options, check the Dollarlabs documentation

Buy X Get Y

Considerations

• The discounted or free item must be manually added to the cart by the customer
• If the discounted/free item is also part of a purchase option with a deposit amount, you might see that amount shown in the cart. It will be correct at checkout, though. This is an issue with the order in which purchase options and discounts are calculated.
