Total Price = Purchase Quantity * Deal Price
The prices of all items added after the threshold item are calculated using the following equations:
Item Price = Unit Price
Total Price = ( Deal Quantity * Deal Price ) +
( ( Purchase Quantity – Deal Quantity ) * Unit
Price )
Unit Adjusted Threshold Pricing Example 1
Items of the same type or group are sold at a unit price of $0.25. The items are on special for
$0.20 with a limit of 3 per customer.
Item Number 1 added to shopping list.
Item Price = $0.20
Total Price=1*$0.20 = $0.20
Item Number 2 added to shopping list.
Item Price = $0.20
Total Price=2*$0.20 = $0.40
Item Number 3 added to shopping list.
Item Price = $0.20
Total Price=3*$0.20 = $0.60
Item Number 4 added to shopping list.
Item Price = $0.25
Total Price=(3*$0.20)+((4–3)*$0.25 ) = $0.85
Item Number 5 added to shopping list.
Item Price = $0.25
