There are 85 sockets of different sizes and three handles for a total of 88 pieces. The handles are black. Numbers 4, 5, and 6 on the Interactive Tour describe the 88-piece total set. You will not get 173 pieces.
That's the way I understood it as well, however, all I got was one set. It also says the 85-piece is black, mine are chrome. Maybe we are all misunderstanding, or they are all missing the 85-piece? I am waiting for an email response from Walmart.
I agree with your thinking... I thought the same thing but we did not receive all of the tools so we are calling them tomorrow to complain.
