Pep boys Unexceptional pricing and WRONG PART Nightmare!!!! Internet

I'm new to Georgia and was having car trouble on Saturday.  I slowing drove into Pep Boys and was advised by them I needed a Control Arm.  I was given a 641.10 quote which was itemized (Labor 448.59, Parts 93.24, other 90.29, tax 8.98) 641.10.  I called around and found a mechanic who towed my car from Pep Boys 55.00, the part Pep Boys said needed replacing was incorrect and the part the new mechanic purchased was 36.90 and he charged me 200.00 to fix my car- total 291.90. And since I'm not from Macon I was not aware of the horrible reputation Pep Boys, Macon had.  Everyone in whom I mentioned this horrific  ordeal ALL said ... "Never go there!
