I returned some parts and a core and it took several days to receive credit on my debit card. This same situation has occurred before.
They are in the neighborhood and the one guy has worked before as a dealership mechanic. I've gone so much that most of the staff even know my name. I dump a lot of waste oil and filters there and no one ever has an issue with it. Oil is overpriced though.
Walmart has better deals and selection: I live in cold Michigan and I can find M1 0w-20/30 and it is $10 cheaper !!! If you think you will have to return anything then consider Autozone !!!
