Context: So I called Sears Saturday to confirm that my dish washer was in and that they had my cel number . Yes on both counts although I found out Sears was not delivering nor installing my dishwasher they had farmed it out . So I called Monday and set up an appointment to have it delivered Wednesday between noon and four .

Answer:

Sears uses the services of a subcontractor for delivery and installation .



Why was the store not going to actually perform the installation of the dishwasher ?
