Hello guys,
I recently found something simple but yet annoying: when you setup a
product's price for a group, you click to make appearing a price form. But
you can't remove this price form for a given group, is to said once you've
setup a price for a group, you can't remove these price brackets anymore. At
worst you empty all fields and validate: the price for this group will be 0.
Phil.
