I just got an email from Ooma regarding a referral discount (and reward) that's good till the end of January. If you buy the hardware from Ooma and use my referral code:

YAY4961

you get $40 reduction in the purchase price, and I get a $20 gift card.

You can get started here:

I don't think the discount works if you buy anywhere else (like Costco).
