my local NAPA is awesome,being i have an older vehicle i used to be in there all the time so they would give me the cheapest price.due in part to the quality of their parts and my knowledge about automobiles,i only go there to get filters now. for the most part they will credit me the core charge so i don't have to pay more when i purchase the item and trust me to return the core,which i always do.
the store is a locally owned former big A parts store thats had the same two guys working there for 20+ years.
