The number of the domain names and the name of the registry are not disclosed.
Also it seems that RetailMeNot and the domain name registry are somewhat connected:
On December 26, 2013, we entered into an agreement with a domain registry company and certain of its subsidiaries. We agreed to pay the domain registry company $4.3 million for second level domains, or SLDs, contingent upon the domain registry company becoming the registry operator for such domains. In April 2015, we used $4.3 million to purchase the SLDs from the domain registry company pursuant to the terms of our agreement. An investment fund holds more than 10% of the outstanding capital stock of the domain registry company and holds more than 5% of a class of our voting securities as of March 3, 2015. In addition, during the period in which the agreement with the domain registry company was entered into and as of the date the purchase of the SLDs was completed, a member of our board of directors was a general partner of the entity that indirectly is the general partner of the investment fund.
My feeling is that the registry involved is Donuts that won the auction for the .coupons string in March. The above $4.3 million purchase was made in April, 2015. Donuts won the auction for an estimated $5 million price beating out Coupons.com that was the other applicant for .coupons. Effectively Donuts got .coupons almost for free. .Coupon is owned by Amazon.
My feeling is reinforced by the fact that RetailMeNot bought 849 New gTLD domain names from Donuts last year. This one of a kind deal (have not seen something similar in all new gtlds) was done in the small window between Sunrise and the start of the Early Access Program(EAP).
.Coupons is currently in the EAP phase and general availability starts in 2 days. No RetailMeNot domains have appeared in the zone files so far from what I can see.
Finally, I wonder of RetailMeNot fired some employees to buy .coupons domain names?
In August 2015, we announced plans to reduce operating expenses in order to realign our cost structure with our current strategic plan. As part of this expense reduction, we have reduced U.S. headcount by approximately 10 percent.
