How to use "Each N-th with Percent Discount" action
The guidance below explains how to set up the rule ‘Each N-th with Percent Discount’ 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 ‘Discount Amount’ field to indicate the discount size. Either leave ‘0’ (zero) or type ‘100’ to give 100% discount.
Step 3. Use ‘Discount Qty Step (Buy X)’ field to indicate the discount step. If you indicate ‘2’ like here, it means that each second item, that meets the rule conditions, will go with 50% discount.
Step 4. 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.
Here’s an example of the rule we’ve created above.
As you can see we have two cameras in the cart and the second camera goes with 50% discount, according to the price rule.
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%.
