That's definitely new(ish). That was historically a big part of their value statement. I've asked them in the past about shipping or picking up a vehicle in the case fo a return from South Florida and the only applicable charge kicked in if you were over the mileage allotment but within the timeframe for a return. Otherwise, there were no separate "shipping" charges.
Interesting that it is a new development for them, coincidentally or perhaps not Carvana has begun charging for regional inventory moves as well.
