Use Quantity Break Pricing on your product to achieve Buy One Get One Free, 3-for-2 and other promotions involving the purchase of more than one quantity of a product to get a discount.
Quantity Breaks are set in Product Manager > select the product > Prices & Delivery tab
BOGOF's: Enter a quantity of 2 with a price that is half the normal price
e.g. Normal price £10 per product, on line 2 enter a quantity of 2 and a price of £5. Then when two products are purchased the total price is 2 x £5 = £10
3-for-2: Enter a quantity of 3 with a price that is 2/3rds of the normal price.
e.g. Normal price £9 per product, on line 2 enter a quantity of 3 and a price of £6. Then when three products are purchased the total price is 3 x £6 = £18
Add other multiples using the above examples to guide you.
