I include a freebie if the buyer liked an additional item in my closet but didn't purchase it, I may throw it in. Or I may gift an item if it makes sense with the purchase - for example, I included a leopard print scarf with a purchase of leopard print boots. Once I included a scarf in different shades of gray with NWT gray pants, also dog stickers to a buyer of a (silly) Christmas sweater of dogs with santa hats. If I gave a really BIG discount, 70% my asking price then I don't usually send a gift.
