# Bundle Percentage Discount

## How this coupon works

**Here**

Buy items(BI) is the minimum 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 discount
Minimum Cart Value(MCV) (optional) is the minimum price of the cart items
Apply coupon on exact quantities (optional) if checked, will apply the coupon only to the specified Buy items and if unchecked, will apply the coupon to more than the specified Buy items

**Example**

Buy 1 get 10% off,
Buy 2 get 15% off,
Buy 3 get 20% off.
Let’s say you wish to purchase 2 items worth total Rs. 2500

**Formula**

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

**Where**

CV = Cart value of n items
D = Percent Discount for n items
MD ­= Maximum discount limit specified for n items

On adding 2 items,
n = 2
CV = 2500
D = 15%
MD = 400

**Therefore**

Min(400, (2500*15/100)) = 375
