Hello Aaron.

Re. definition. Coupons are considered separate line items with a negative price in the shopping cart. You cannot, for example, use them explicitly to reduce the displayed cost of just one item say - but you can engineer the same effect by applying the right discount. Depending on how you create your coupon, you may be able to send in some explanatory text (options 1 and 3 below).

In Google Checkout, there are 3 ways of applying money off to a shopping cart.

1. Send in the adjustments as negative priced line items. 2. Use the Google hosted coupons feature in the merchant centre. 3. Use the coupons / gift certificates support in the merchant calculations API (not in the UK right now).

So, in reality, if you want to be able to add free gift lines and you dont want to duplicate effort, option 1 is the way to go. Most of the merchants I have worked with collect the coupon code on the shopping cart page - i.e. before the user clicks on the Google Checkout button. This allows you to send through free gift line items as as well as money off items.

Will that work for you? S...

Has anyone implemented google checkout on an existing site that uses promotions? There are a couple of issues I have and was hoping someone else had dealt with them before.

The first is what's the definition of a coupon? Is is anything that reduces the total price of the basket or includes items at a reduced or zero cost? Or is it limited to reducing the basket value by a set amount or percentage or is it something like including a free gift?

I ask because section 2b of the Policy document (http:// checkout.google.com/seller/policies.html#4)  says: "If you accept coupons on your website in any way, you must allow buyers to provide coupon code information in the Google Checkout checkout process."

So if we have customers enter in a promotion code that, say, gives them a free gift do we also need to allow them to enter that code when they enter the google checkoout process.

We realise it is possible to use the google merchant centre to manage promotion codes, but this would result in a duplication of work. So we would need to implement the merchant calculations API if customers must be allowed to enter promotion codes using google checkout.

Thanks for any help.
