Pay COBRA premiums using HSA

[free4now]

I was glancing through the HSA basics brochure at:

http://www.treasury.gov/offices/publ...english-06.pdf

and noticed something surprising. In the last column it says that an HSA can be used to pay COBRA healthcare insurance premiums!

If that's true, it seems like a no-brainer to open an HSA for almost everyone who uses CORBA insurance. Who wouldn't want the tax deduction? I feel like a dunce that I've been paying COBRA for a few months now without having noticed this.
