I recieve all the stuff couriers drop off, sign for it and check the contents to make sure nothing is damaged and everything is there. Usually only larger companies have recievers otherwise the shippers do both jobs. I work for Delta Controls, we manufacture HVAC systems and lighting controllers. Probably every 1 in 5 buildings you visit during your daily routine will be running our systems.
And no I am not willing to pay for my ECU by "recieving".
