i know alot of vendors charge a little extra than normal but that extra 5 bucks for the flag is better than driving in to town to get a new one (by then i would have called it a day ).
i'm kinda glad thier out there back in the day we had nothing .
it's hard to say what is really needed other then what is already out there . only thing i can think of is check out what the vendors are actually carrying and sell what they don't .that you know people would need .
