My guess is that the guys at Seyberts ordered a bunch of IPT tips back when the gravy train was still chugging along and now they're stuck with a bunch of IPT tips that nobody wants to buy. They offer them as a way to sell them and be done with 'em otherwise the tips are only good for collecting dust. Just a guess.
Why else would a respected pool company such as Seyberts be actively trying to sell IPT branded stuff?
