Amber has helped me a couple of times in person and she's great - very friendly and knowledgeable.
She performed a complimentary check on my alternator and sold me the replacement part that I was sure I needed. A week later it turned out that it wasn't the alternator (not her fault all she did was tell me the reading - I was going by a diagnosis from Sears :-(
I brought back the part with my receipt and was immediately given credit back to my card - easy-peasy!
I like that the store employs a couple of women. Virtually everyone I've dealt with (male or female ;-) is very nice, professional and happy to help or answer questions.
The amazing part is that the store is open until 10 pm most nights (check for exact hours) -- so convenient for those of us that turn into "vampires" in the scalding Phoenix summer heat!
Just now Bobby helped me by confirming that my new parts had come in -- nice guy!
I'm paying off my car loan this month and already things are flaking out so i expect to need more help in the future and I'm definitely grateful that this OReilly store is almost right around the corner - I'll be back!
