The guide below explains how to set up the rule ‘Percent Discount: each 2-d, 4-th, 6-th with 15% off’ of Special Promotions extension.
With this rule you can create promotions like
‘Each second (third, fourth, etc.) item for 50% off (or for free)’
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 ‘Percent Discount: each 2-d, 4-th, 6-th with 15% off’ action for the ‘Apply’ field.
Step 2. Use ‘Each N-th’ to specify a number of items a customer should buy to get a discount.
Step 3. Specify the appropriate conditions for rule applying. If you would like to provide for free or discount items only from a certain category or of a particular brand, etc, please indicate the category, brand, other conditions here.
And here's the result for the rule above.
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 second for 50% off, in our case the $50 product will discounted by 50%.
