How to use "Each N-th with Fixed Discount" action
The guidance below explains how to set up the rule ‘Each N-th with Fixed Discount’ of Special Promotions extension.
With this rule you can create promotions like
‘Each second (third, fourth, etc.) item $50 (100, 200, etc.) off ’.
Let’s observe the steps of the rule configuration.
Please open Admin Panel > Promotions > Shopping Cart Price Rules (click ‘Add New Rule’ button) > Actions.
Step 1. Choose ‘Fixed discount: each 3-d, 6-th, 9-th with 15% Off’ for the ‘Apply’ field.
Step 2. Use ‘Discount Amount’ field to indicate the discount size.
Step 3. Use ‘Maximum Qty Discount is Applied To’ field to indicate maximum number of items for which the discount should apply.
Step 4. Use ‘Discount Qty Step (Buy X)’ field to indicate the discount step. If you indicate ‘3’ like shown below, it means that each third item, that meets the rule conditions, will go with $70 discount.
Here’s an example of the rule we’ve created above.
As you can see we have three products in the cart and the third of them is $70 off.
The calculation for ‘Each N-th with Discount’ action works this way:
1. All items that meet the rule are counted and sorted by price from highest to lowest. Let’s say you have three items that meet the rule. They cost $50, $70 and $30. The extension will create a list with such order: $70, $50, $30.
2. After that each n-th product from the list is discounted (or made free). So if the rule is set as each third with $70 discount, in our case the $99 product is discounted by $70.
