# Bundle On Quantity Percentage Discount

Video: How To Configure 'X Percentage Value' Coupon

## How this coupon works​

Here

Buy items(BI) is the minimum number of items to purchase
Discount items(DI) is the partial number of items eligible for a discount
Percentage Value(D) is the fixed percentage discount
Maximum Discount Amount(MD) (optional) is a limit to the total discount

Example

Buy 3 items, get 2 of them at 10% off.
Let’s say Item 1 costs Rs. 5495,
Item 2 costs Rs. 6495 and Item 3 costs Rs. 9995 and Maximum Discount is Rs. 2000

Formula

Coupon Discount = Min(MD, (DImin(all)*D/100))

Where

DI = Discounted Items D = Percentage Discount
MD = Maximum discount limit DImin(all) = Sum(DI Minimum price in cart)

In this example

BI = 3 DI = 2 D = 10 CV = 5495+5495+9995 = 21985 MD = 2000

Therefore

DImin(all) = Sum(2 Minimum price in cart) = [5495+6495 OR 9995+5495 OR 6495+9995] = [11900 OR 15490 OR 16490]
= 11900

Min(MD, (DImin(all) D/100)) = Min(2000, (1190010/100)) = Min(2000, 1190) Min(MD, (DImin(all) * D/100)) = 1190
