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
Cart value
