Also note: I don't mean to suggest Arm & Hammer is necessarily bad. I know some people here have happily used it, and, in fact, I just got a jug last week. (Too early to judge my experience, but, so far, it seems to be working fine. Although my laundry is seldom hugely demanding--most of what I need is freshening, not removing stains from hell.)
It's just seems puzzling to try to market with a compare to a budget brand. Even if the comparison is probably more apt than one with, say, Tide.
