What is Gift with purchase?
A gift with purchase is a free item added to an order when the shopper meets a condition, usually a minimum spend or the purchase of a particular product.
The gift costs you its landed cost, not its retail price, so set the trigger well above the point where the order is already profitable. The free gift threshold post shows how to pick it.
Gifts differ from discounts because the shopper sees a tangible extra rather than a lower price, and the price of the main product stays intact.
