Formula = (X+Y) * (M/Y)
Where
X = number of items purchased
Y = number of free items
M = Maximum number of free items allowed

For example:

Buy five and get two free with a maximum of four free items allowed.

Where
X = 5
Y = 2
M = 4
Maximum Qty Discount = (5+2)*(4/2)=(7)*(2)=14

Buy five and get three free with a maximum of nine free items allowed.

Where
X = 5
Y = 3
M = 9
Maximum Qty Discount = (5+3)*(9/3)=24

Buy 20 and get two free with a maximum of 20 free items allowed.

Where
X = 20
Y = 2
M = 20
Maximum Qty Discount = (20+2)*(20/2)=(22)*(10)=220
