Discount Calculation

The calculation of the discount will proceed in the following manner:

Discount Calculation for a Single License
unit price x discount rate(%) = discount

Take the up-to-date total of 20
licenses as an example, the discount
for each license will be:



$499.99 x 15% = $75.00

Total Discount Calculation
unit price x discount rate(%) x up-to-date total = total discount

Take the up-to-date total of 20
licensesas an example, the total
discount will be:



$499.99 x 15% x 20 = $1,499.97

Bonus Related Calculation

The discount rate for the first 19 licenses is 10%, when the 20th is ordered, all the previous 19 licenses will enjoy the same discount of 15% as the 20th does, which means a bonus from the previous 19 licenses will be added on top of your current discount for the 20th.

Bonus from the previous 19: $499.99 x (15% - 10%) x 19 = $474.99
Price of the 20th after discount: $499.99 - $499.99 x 15% = $424.99
Price of the 20th after bonus: $424.99 - $474.99 = - $50.00

A negative amount indicates that your 20th key is free and you have a credit of $50.00 on your account for your next purchase.

Reminder once again:
If your payable amount is zero or negative, you will still need to pay $0.01 to complete the transaction as PayPal enforces a minimum payment amount requirement of $0.01.
