I spent a dozen minutes trying but all sound names that came to head were taken. Try using domain name generators from Namecheap.com , godaddy.com , Name.com , Domain.com , DomainName.com - maybe some of these will be of use. However, bright names are hard to find on forums or in generators... They usually appear in your headd and strike you like a punch to the nose. Good luck trying, though!

You can try some of the domains that my new site www.helgesdomaingenerator.com can generate But for a retail site you could try these: Dealztoday GetMahCoupon CheapoSkeato
Retialmenot is not a good name. You see it as a good domain cause some million $ were invested in it. But if didn't exist and I would suggest it to you ... I think you would skip it. So any name can become a brand if you invest some tons of money. If not you can compose a name with keywords: couponsanddiscounts + extension.
Yeah, I'm not a huge fan of retailmenot. The domain and the site lol. I liked the domains I suggested hahaha
