The expression "throw in" is often used when someone adds something extra to what they are already offering or when they offer something at no extra cost. For example, if a person is selling a car and adds in a free set of tires, they may say, "I'll throw in a set of tires for free." Or, if a person is ordering a meal at a restaurant and the server offers a free appetizer, they may say, "We can throw in a free appetizer for you." Essentially, "throw in" means to include something extra or to offer something for free as part of a deal or transaction.
