My "delivery address" is 11/3 blahblah street. The /3 bit means that my address is flat 3 in block 11.. my front door is on the second floor. Royal Mail couldn't get away with leaving my post downstairs so i don't believe that any supermarket delivery should.
I am not 39 weeks pregnant, I am able bodied, but that isn't the point.
I ALWAYS expect my sainsburys shopping to come to my front door and it always has done. I would not order from Tescos having heard that they might leave my shopping downstairs in a communal staircase and not inside my private residence.
