An
£83.15 Railcard Off-Peak Return Stalybridge - Bournemouth route Not via London is suitable for the outward leg of your journey, travelling from Manchester to Bournemouth via Oxford. It's not valid Mon-Fri 0430-0929.
A
£101.20 Railcard Super Off-Peak Return Stalybridge - Bournemouth route + via Doncaster is suitable for almost the whole of the return leg of your journey, travelling from Bournemouth to Stalybridge via London, Sandy and Doncaster. The return leg is valid by any train from Bournemouth to London, on the tube from Waterloo to Kings Cross, and for departures from Kings Cross Mon-Fri 0906-1459 and then from 1900 Mon-Thu, from 1815 Fri.
To travel outward via Oxford and return via Sandy, you should buy the £83.15 ticket and excess the return leg of the journey
only to the Super Off-Peak Return route + via Doncaster. This costs half the difference, that's £9.05, making a total of
£92.20.
If you don't already have a pass or ticket valid for rail travel in Greater Manchester, you'll also need a
£3.05 Railcard Anytime Day Single Stalybridge - Manchester CTLZ, and to catch a train which calls at Stalybridge.
