Show merchants that do not stock product

Hi david,

Really sorry for starting this thread, as I know it has been talked about before. Could you point me to the post where you tell us how to show all merchants, even the ones who do not stock the product in question.

I read about it a few months back. For example, if someone has about 10 merchants on their PT site, all 10 would always show in the product comparison tables. The merchants who do not stock the product would just show "does not stock" or similar but can be still visited by the user.

I know there is a post about this somewhere but I can't find it using search.

Thanks.
