I recently created a new view used for listing Ubercart products in Drupal 7 and didn't want the 'quantity' field beside 'Add to cart' button.
Here's how to 'get rid of' the quantity field:
- Open: 'yourdomain/admin/store/settings/products', where yourdomain is your actual Drupal installation,
- On the 'Product settings' tab disable the 'Display an optional quantity field in the Add to Cart form.'
Save settings and voila, this is it ...
