How do I set the margin on my catalog?
Click "MY CATALOG" on the "MY STORE" menu. The margin you wish to apply across your whole catalog can be entered in a blue box located at the very top of your catalog page (as a percentage or in euros).
By default, the margin rate is set to 200%. You can change and adjust it as often as you like.
This margin rate will be applied to every product in your catalog.
