Ubercart

To change the order of the Catalog listing, go under Home › Administer › Content management > Taxonomy and click the 'list term' link next to Catalog.

You can then drag-and-drop the items and order them as you would like them to be presented.

Hope that helps!

If you use views to order your products, you should be able to better shape the outcome to your requirements.

I feel like a damned idiot. I do this all the time and after not touching the catalog for a while I spent a whole hour looking all over the admin menus for it.

Turns out it was right under my nose.

Here it is: How to re-order products in the catalog.

Go to the product node
Click edit
Under Product Information there is a list position option with a drag down menu with numbers. Order accordingly from lowest to highest.

Good luck!!

I would recomend you to use http://drupal.org/project/draggableviews

I totally agree to the above replies. Dragging items can solve your problem. The link above is so useful.

This "draggableviews" module seems perfect.
I'm using a custom views list of products for my back-office store and could indeed use this module for ordering the products,
but my front-office store uses the default ubercart catalog that sort the products according to the "list position" field (the combo in the "product information" bloc)
and I can't find this field in the Views list of fields !
How could I do then ... ?
Someone has an idea ?
Thanks.
