I went into my local parts store to buy a set of spark plugs. I was amazed when he said they were $7.86 ea. That was enough to make me shop it online. Went to Rock Auto and the same plug was was $5.36 and on top of that there was an A.C. Delco mail in rebate for $3.00 per plug. Got curious and called my dealership and asked for pricing. The plugs were full price plus markup plus 1 hour labor to change plugs came to $180.00 So Rock Auto saved me well over $100 bucks and will be my first place to shop for any parts for my future projects. Thanks so much!!
