I need to buy 4 bottles of ARX for household vehicle applications. What I can't figure out is:
Why is it cheaper, on a per bottle bases, to buy 3 instead of 4. Is it true that the fourth bottle reverts back to the full retail? I know that the three bottle offer was to accomodate those who own diesel powered trucks, with large oil reserves, but what about the poor guy that has two beaters in his driveway?
