Urgent Question on Code Placement for Google Checkout Prohibited Items (General)

Hey Gang,

First - I'm posting this in "General" because even though it's about Google Checkout code, it really has little to do with the actual Google Checkout module in Zen, but more about Google Checkout's policies.

They are threatening to suspend my Google Checkout account because we have some prohibited items (ammo, ammo accessories) on our site at McKinnonOutdoors.com.

Basically, they have given me this code:

<img src="http://checkout.google.com/buttons/checkout.gif?merchant_id=xxx&w=180&h=46&style=white&variant=disabled&loc=en_US">

This code is to be placed on all prohibited products - which I've done. However, once you add the product to your shopping cart, it doesn't realize it's a prohibited item, and the "GoogleCheckout" badge is still active.

So, how can I identify a certain class of products so that they are NOT eligible for GoogleCheckout ... the code above is basically an image call, and I'm not sure how it's presence on the product prevents the GoogleCheckout badge from being active, and of course, once you add it to your cart, the stuff in the product details doesn't carry over.

Thanks!
