CardRetail.com ...... what card? poker card? pokemon card? postcard? greeting card? photo card? game card? credit card?
As you see, it's too generic and can't be identified in something. So i would say reg fee, from a domainer point of view.
GetNewApp.com.... pity, it's singular. The plural would have some value, singular form is killing the domain.
However it's not as bad, i think you can raise up to mid $xx for this.
