### 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:
``````<?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']
