I got mine at Greentop ( still deal there ), and I to watched pennies . As for Bob's on Grandby St. he is still the highest place in Va. to by ammo IMHO . Like I said I compared to other 10 round boxed of turkey loads not 25 round boxes of # 5's That I also used which were cheaper shell for shell.
As a side story , The first gun I got from Greentop I got from the guy who owned it . It was back when surplus ammo sat around on the concrete floor. I wanted a gun and was looking at it . He ask if I wanted to take it home . I said yes but didn't have enough cash. He ask what I had . I told him and he said heres the deal I give you the gun and two boxes od ammo for what you got and you buy ammo from me as long as I got as good or better price than other stores . That was over 30 years ago and I still check with them first when I buy ammo. I still deal with his sons , good folks all of them.
