He didn't get hosed, it's just an average deal, but he didn't get an awesome deal either. There's just no need to be buying 30quarts unless he needs to use that in the next few months.
For example:
Amazon has 6packs of ultra with a new $7 coupon+Pennzoil $5 coupon+fram ultra filter.
so 6quarts+fram ultra filter is 48-7-5=36.25 for 6quarts+filter.
Pepboys has a 35% off $150 of regular price items. So if you buy that much PUP at their rack rate, 35% off gets you the same price as an oil change special, without getting filters you may not want.
