You do not need to ship to a FFL (Federal Firearms Licensed) dealer for ammo. It can be shipped directly to a persons home.
The only reason I suggested Gunbroker.com was because you can reach the audience specifically looking for this ammo. The chances are slim anyone in your direct area would be looking for it, but it could happen.
If worse comes to worse, check the local gun stores and pawn shops in your area and see what price they will give if they are willing to purchase it.
I do wish you the best of luck.
