I'd also recommend checking fares for Newcastle to Glasgow Queen Street/Central, because the stretch between Glasgow and Edinburgh is open ticket, despite being fixed between Newcastle and Edinburgh.
I have had the 18.30 EC out of Durham in 1st for just over £20. 16.50 (think it's a few mins later these days) crossstinky for £13 home the next day.
Put in a random trip for 7/7. Cheapest is £17.50 there. £18 back the next day. Both direct.
