# Buy X Items Get Y Items Free

## How this coupon works

**Here**

Buy items(X) is the minimum number of items eligible for getting more items for free
Get Free Items(Y) is the number of items you will get for free
Minimum Cart Value(MCV) (optional) is the minimum price of the cart items

**Example**

Buy 2 items, get 2 items free.
Let’s say Item 1 costs Rs. 2000,
Item 2 costs Rs. 1500 and Item 3 costs Rs. 3000
and Item 4 costs Rs. 1000

**Formula**

Coupon Discount = Ymin(X+Y)

**Where**

CV = Cart value of X+Y items
X = mandatory number of items
Y = number of items for free
Ymin(X+Y) = Sum(Y Minimum price in X+Y items)

**In this example**

CV = (2000+1500+3000+1000) = 7500
X = 2
Y = 2

**Therefore**

Ymin(X+Y) = Sum(2 Minimum price in 4 items)
Ymin(X+Y) = Sum(1500, 1000)
Ymin(X+Y) = 2500
