Buy 1 Get 1 Half Off

Hi,
I know there are similar threads in the forums about discounts based on number of items in the cart, but I believe this may be more complicated. I need to set up a discount rule that essentially says the following:

If NumItems >= 2
Give 50% on lowest priced item

The problem is twofold. First, I don't know which items will be added to the cart or in what order. Second, I can't figure out where to grab the product IDs and/or prices of the items that are in the cart so that I can do the comparison in the eCart file to apply the discount.

Any help would be much appreciated.

to find the lowest priced item in the cart, you could add a loop through the cart object simialr to:

<?php

$cartName->MoveFirst();

$price = $cartName->DisplayInfo("Price");

while (!$cartName->EOF())      {

  if($cartName->DisplayInfo("Price") < $price) $price = $cartName->DisplayInfo("Price");

  $cartName->MoveNext();

}

$cartName->MoveFirst();

$_SESSION['50PercentOfLowestPrice'] = $price / 2;

?>

where cartName is the name of your cart object.

This will compare each price in the cart, and if it is less than the previous one, set the $price variable to hold that value. It also creates a session variable that can be used in a flat rate discount.

On the discounts tab, create a new discount, using the trigger Number of unique items is greater then 2.

Use a flat rate calculation of: $_SESSION['50PercentOfLowestPrice']

Jason,
Thanks for the quick reply. Our Marketing Dep changed their mind on what promotions they want to run. But, I will be trying this out as I know they will eventually want to run this type of offer.

you're welcome.
