How does Paladin Point of Sale determine BOGO refund amounts?  When an item that was part of a BOGO sale is returned, the system returns a percentage of the retail price depending on the total amount of the discount. Here are two examples.

## Buy 2 get 1 free: All items are the same price.

Original Invoice:

• 3 x 13.99 = 41.97
• -1 x 13.99 = -13.99
• Sub Total before Tax of 27.98

Return Invoice:

• -3 x 9.33 (approx.) = -27.98

Explanation of the return invoice:

• 13.99 (discounted item) ÷ 41.97 (total of all sale items before discount) = 33% discount.
• When sale items are returned, the discount is applied to each item.
• (13.99 x 33.3% = 4.66; 13.99 – 4.66 = 9.33)

## Buy 2 get 1 free: Items have different prices.

Original Invoice:

• 1 x 5.99 = 5.99
• 2 x 13.99 = 27.98
• -1 x 5.99 = -5.99 (The discount is always the lowest retail item that you get for free.)
• Sub Total before Tax 27.98

Return Invoice:

• -2 x 11.52 = 23.04 (approx. due to rounding)
• -1 x 4.93 = 4.93 (approx. due to rounding)
• Sub Total before Tax 27.98 (Rounding adds a penny, so the actual shown value would add up to 27.97.)

Explanation of the return invoice:

• 5.99 (discounted item) ÷ 33.97 (The total of all sale items before discount) = 17.63% discount.
• When sale items are returned, the discount is applied to each item.
• (13.99 x 17.63% = 2.47; 13.99 – 2.46 = 11.53)
• (5.99 x 17.63% = 1.06; 5.99 – 1.06 = 4.93)
