I just bought some ACDelco spark plugs yesterday, and was pleased to learn there's a rebate on them. I might not have thought to check the receipt for that, so am glad the store clerk (shout out to Auto Zone) let me know. The rebate per plug ranges from $1 to $2, depending on which type you buy. I'm posting this to let everyone know, in case they buy them, because if the clerk hadn't pointed it out, I might have missed out on saving some $$. The rebate runs between 2/15/15 and 12/31/15, and is on plugs purchased OR installed.
