Bennington Transfer Station / Scale House

I don't think there is a way online. You might be able to call the Town Clerk and they can probably mail you one.

Cash or check I know for certain, but last time I was there I think they were set up to use credit/debit cards. You can call there's always someone available at the gate.

No, they'll take them for free as recycling. If you want to sell scrap, you need Foster's on Benmont, or the scrap metal place over the NY line on 67 like you're going to Hoosick.
