What happens at Point of Sale?

Question: So what happens at the Point of Sale when a item is sold this has two different unit prices for the same UPC?  
 
Answer: The system presents to the sales clerk a screen to select the correct unit of measure and related price to complete the sale.  In this example, the UPC "0182000010620" was scanned or "1062" was entered and the system prompted the user to select between the  24PK, 6PK, 12PK or a single unit of EACH.
 
 
The selected quantity with the appropriate price will then be entered into the invoice.
