@Mark How is this worth $50 off? The link you provided (http://go.ooma.com/referral/?referral_code=NEK9052) claims a $149.99 price. But I can buy it from Ooma.com (here http://ooma.com/shop) for $149.99. ^:-/
Using my link you can get the Ooma Telo for $139.99 which is $50 off of the retail price. As you point out, ooma.com is currently running a sale at $149.99, but using my link you can still beat this price by $10. Happy savings!
$179.99 (suggested retail on Amazon) - $50 = $129.99 not $139.99 If the price with the code is $139.99 and is a $50 discount, then where is it that the retail price is $189.99? Seems like a $10 discount, not a $50 or even a $40 discount.
Note, the link the OP was edited and corrected to get to the $139.99 price. :)
Suggested retail at J&R (http://www.jr.com/ooma/pe/OOM_1000210100/) is $190.99 and suggested retail at Newegg (http://www.newegg.com/Product/Product.aspx?Item=33-888-002) is $249.99. So in my post I could have said that my code offers a discount of $110. The important thing to remember here is that by using my code you can get the Telo for only $139.99, which is a great deal no matter how you slice it.
