For years I have been picking up drywall, lumber and even fixtures such as bathtubs and toilets and bringing them to a home we were remodeling. I've done so without charging a delivery charge (which Home Depot and Lowes would do). I did that in the belief in might help me win the bid. However, after looking over my fuel bills, I am starting to rethink this. Should I be charging for pickup and delivery, and if so, do I match the big box stores' delivery charges? Looking for opinions.
