I went to the Pontiac dealership and got a price quote for the brake shoes for the drum brakes on the rear of my 2000 Grand Am
Part number 19152644, shoe kit, $114.48, $123.35 after taxes
So I go to Autozone.
Part number #199277 720 , $21.99. $23.69 out the door.
It may be that the dealership brake shoes are better quality, longer lasting, and impressive materials... but when I can get 4 sets for less than one from the dealership, and those 4 sets will last twice as long as the longest lasting set the dealership will have... the choice comes down to dollars.
What really makes it all clear? http://www.oehq.com/acdelco-parts_19152644_ACD_AC%20Delco%20SHOE%20KIT%20R.htm
the same parts from an online outlet for $67.65, about half the dealerships charge. What rip off artists!
