product price setup

[mc12345678]

yes, I got it.
Here the customer wants to have only a product as cubic zircon and list all the sizes (he carries many sizes) under that item.
Thank you for your feedback

So like I tried to say earlier (but looking back didn't do a good job) and like dbltoe is saying:
Cubc zircon is the product, price 0, set the product priced by attribute, set the units to 10.
Attrbute controller add all the attributes desired (sze) with price per "item".

Customer required to enter quantities of 10 to add the product to the cart and away the store goes...

There are three or more ways to do this but, the OPs customer wants drill-down. They will just have to wait or spend big bucks for programming.
Maybe we should do a fundme for someone to do this. There are many here that want this but the current 1.5.x series makes it extremely difficult to do. Conor was very close at the time of his passing.
