discount if 2 items appear in cart

Hi,
I am trying to setup a discount if there are 2 specific different items ordered at the same of 10% and I am having trouble figuring out the proper discount code setup. I just want to discount the price of those 2 items but not any other products or the subtotal. Additionally, is there a way to setup an "add to cart" button that will add these two items at the same time from static pages. (i.e. ItemID "a" & "b") Thank you.

Does anyone have any ideas on this? Thanks.

for the discount, you will need to add an additional column to the cart object to mark the items that the discount applies to. For the sake of example, lets name this new column "discountable"

In the add to cart button bindings, set this column to a value of 1 for the 2 items that the discount applies to and 0 for all other items.

Now when creating the discount rule, use the following settings:
Triggers:
Number Of items with a specific column value:
If the number of items where 'discountable' has a value of '1' is '>=' a value of '2'

Calculation:
Based on items With A specific value:
Total Of 'Quantity' Where 'discountable' has a value of '1' 'time' '0.1'



to add the 2 items at the same time, use the eCart Add to cart server behavior.

Add a form and a submit button to your page, then go to the server behaviors panel, click the plus button and select eCart -> Add to Cart.

Set the trigger to Button <Your button name here> pressed

on the bindings panel, set the product information for the first product. Repeat this and add a second add to cart behavior using the same trigger, on the bindings panel add the product info for the second product.

Thank you, this seems great. However, I need to give each product a different "Discountable" column value so that the customer will need to have both seperate itmes in cart and not just two of one of the items. It was clear that I could add two triggers, one for each product. How do I set the calculation to include both items? "...Where 'discountable' has a value of '1 AND 2' 'time' '0.1'" What do you put in place of the 1 AND 2? Thank you again.

ok, in this case, leave the discountable column value as 1 for both products and use the triggers:

Presence of item in cart:
if Item '<ID for prod 1>' 'exists' in the cart

AND

Presence of item in cart:
if Item '<ID for prod 2>' 'exists' in the cart


where <ID for prod 1> and <ID for prod 2> are the ID values for the 2 products. leave the calculation as described before.
