Typically, there's at least a 50% mark-up on parts at repair shops because they have to warranty the parts as well and for overhead.
If you find a mechanic that does side work at his/her home (like mine), you can buy the parts (or use the mechanic's discount) and have them replace them for less. Or you can replace them yourself. They do take a while to replace - I don't think their labor charge is unreasonable.
Or, you can try buying the parts and then seeing if a repair shop will install them - but you will probably have to sign a waiver of warranty. Most repair shops won't do it in my area. I wish you luck!
