# Bundle On Quantity Percentage Discount

## 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, (11900*10/100))  = Min(2000, 1190)
Min(MD, (DImin(all) * D/100)) = 1190
