Comment Re:Will Tesla buy them? (Score 1) 193

Almost every supermarket in the US has filled tanks for exchange and the price is indeed fixed at about $25 bucks a pop. But I stopped going there when I found out the local Flying J truck stop would refill my tank for a third to at most half that. The fixed price exchanges are gouging you even if you bring in a fully expended tank.
