Buy X quantity of product from category A, get Y quantity of the same product for free.

To limit the free product to categories A, B, and C, set the action as follows:

If ALL of these conditions are TRUE:
SKU is one of D123, E123, F123

Use the following formula to determine the correct value for the Maximum Qty Discount:

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 5 Get 2 Free with maximum of 4 free items allowed.

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

Buy 5 Get 3 Free with maximum of 9 free items allowed.

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

Buy 20 Get 2 Free with maximum of 20 free items allowed.

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