I dont like being ripped off at the auto shop

I cant always have my boyfriend come with me so I have to go to like 4 or 5 different auto places to compare prices. They said I need front brake pads and a caliper repair. My car was sounding like it was dragging loud. The prices I got for total including labor were $430, $239 and $140. Ya see? 🙄 😡 Next time Im gonna ask to buy the parts myself and just pay for labor
