Everything is located in Lomita and is available for pickup on Sundays, random week days and evenings after 5:30. I do have a cherry picker to help load stuff into your truck.
I would rather not ship this stuff due to its size, so if shipping is a must, buyer pays ALL expenses associated with the shipment.
