A 'nice' feature of the Great Northern ticket machines is that they tell you what you can't buy up front on the home page - saves you time trying to find them and failing. A nicer feature would be if it actually sold most of those 'not available' tickets. It's not rocket science

@RailfuturePsngr Yes, but actually GroupSave Discounts are available... Doesn't fill you with confidence if the home page is wrong

@RailfuturePsngr Idea: you put what ticket you want into their website before you leave and it generates a QR code that the machine scans to get the right ticket...
