Maybe I don't know what I'm doing, but several times now I've tried using the NRA "discount number" at various travel related businesses for the "super discount". I've never gotten a better deal through the NRA program than I get just doing a Travelocity search. Today I was booking some travel to Florida. Every hotel site said, "This discount code not valid at this location." When I went to book a rental car, the NRA price was in one case equal to, in the other cases higher (though by very little), than a standard Travelocity car search.
So any of you ever get good deals through the member discounts??
