Dunno if worth hassle for just 10% When I get 5 points, transferred to reserve = 7.5 % back, so to save 2.5 not worth it 
Travel spend is 3X on Reserve so you get 3 points not 5. just FYI
unless you are referring to buying gift cards at office supply
and yes 10 percent seems really low and I would not buy either but its a supply and demand problem. . Not a lot of sellers selling at .85 or below. Once in a while you get them
