The 2-Oreilly's closest to me are like night & day, at one it's like your invisible or talking to bricks, at the other they greet you asking how they can help & will go out of their way to try to find stuff.. In the past they have ordered name brand parts & can get just about any of the speed stuff in No-Freight in a day or two but I always go in with the part number I want.
I get a good discount at my local o'reilly store plus eric the manager there knows parts.2 blocks from my house and he'll beat auto zone,napa,etc prices for me.i've have selling GM parts for 27 1/2 yrs now and i know what stores to in and what ones not to.i do know one thing for sure i'll NEVER go back to pep boys again.worst parts people i have ever seen let alone not being able to speak english.
