3 for the price of 2

I need to create a discount rule that looks at each line item in the cart and if the quantity of that item is greater than 2, I want to discount the product by 34%.

In the eCart setup I've started a new rule called Quantity.
I've selected Number of itmes with a specific column value
I've picked Quantity as the field

Here's where I'm confused.

What I want to say is "Where Quantity is greater than 2" or "Where Quantity is 3 or more", but the option I am presented with is:

If the total number of items where Quantity has a value of _____ is ___ a value of ____

This seems to be taking me towards, if 1 or more columns has 1 or more items in it then apply a discount to the whole cart.

I only want to discount that item where there are 2 or more purchased.

rules that should be applied on a lime item basis should be created on the Calculations tab.


to create a 34% discount on 2 or more, modify the TotalPrice calculation to;
(([Quantity] >= '2')?([Price]-([Price]*0.34)):[Price]) * [Quantity]





this basically says:
if the quantity is 2 or more, the price of each item is [Price] - ([Price] * 0.34) else the price of each item is [Price]

This worked perfectly on the cart and confirm pages but we just discovered that it does not flow through to PayPal.

The PayPal connection takes the Item Price and Quantity and re-does the math. It is not capturing the revised row value and since the Discount is done without a Discount rule, there is no Discount at PayPal.

Is it possible to create a Discount based on this same logic, instead of altering the line price.

ie:
Items go into cart
Discount rule says: if any row above has 3 or more items then discount amount is total of that particular row times .34? and have it cumulative?

This way, the Discount field would be populated.

Not really, you would need to create a seperater rule for each item ID in your shop.

a better way is to create a new calculation named truePrice as:
(([Quantity] >= '2')?([Price]-([Price]*0.34)):[Price])



and instead of passing the price to paypal for the items, change it to pass the truePrice instead
