Hello, I will be returning from Newton Stewart to Preston on June 2. I am trying to find most enconomical way of doing so. I can take bus from Newton Stewart to Preston but it cost 28 gbp and in us dollars it's 56 which is a lot. I can take a train from dumfries to preston for 10 gbp but do not know how to get from newton stewart to dumfries. tried to look but either too dumb or can't find it. can anyone give me any advice? I would prefer to leave mid afternoon - i only need 1 way as friends driving me down earlier in week after we spend couple of days in edinburgh. thank you in advance..
