I see a lot of etailers that have free shipping sales and wonder how they can afford to do this...I can see it with a minimum purchase but a lot of them do it without a minimum. What happens with all the $10-$20 orders? If I paid shipping on a $10 order of tarts, it would actually be spending money for them to take my tarts in most cases. lol Can you write off the cost of this free shipping on your taxes at the end of the year or something? Just trying to figure this one out...
