Do the old HOB filters have to work? I have a couple of lousy ones and one with a cracked inlet pipe. It seems kind if crazy to trade in junk for good merchandise. Have they done this sort of thing before?
I think I'm "hooked" :
in and will check this out.
Being a skeptic, the ad re: HOB's is qualified "while supplies last." Not much consumer opportunity (or cost to AA) if supply is only X amount on Saturday morning.
I am a big AA fan when it comes to rock and gravel - they have some unique stuff - not cheap.
