Display Marketpress Widget on all product pages in combination with Appointments+


I'm running Appointments+ with Marketpress. I have the Marketpress widget installed in the sidebar & have it filtered to display only products with a certain tag. I have elected to show the price AND an "add to cart" button however these only show up in a particular category (optional extras), not in the category with the Appointments+ products (and ideally, the only category that I do want the full list displayed). So I'm wondering

1) How can I force the price & button to show in the sidebar of these pages
2) Is it possible to restrict the sidebar to only one category?

Category where the price & button ISN'T showing http://bit.ly/13eZboh

Category where the price & button IS showing http://bit.ly/11cj9vN

Thanks in advance :slight_smile:
