I need some help about the best way to add alternative measurement units (unit packages) to our products.
There is an online store that sells lubricants (motor oils), so we have a product named "Lubricant Sample SAE 5w-30 1lit.".
The default unit is the "piece" (1 piece = 1 unit), but the store also sell that product to a carton "box" (or package) that contains 12 pieces (1 box = 12 units) and of course to different price (usually price = unit price x units).
Is there anyone who know how is the best way to implement that?
