Poynton's associated routeing poynts (

) are Crewe, Stockport, Stoke on Trent, and Wilmslow. Liverpool Lime Street is part of the Liverpool routeing group. Poynton to Liverpool Stns SDS costs £14.30.
- Crewe to Liverpool Stns SDS is £11.10, so Crewe is an appropriate routeing point.
- Stockport to Liverpool Stns SDS costs £14.30, so Stockport is an appropriate routeing point.
- There is no fare to compare for Stoke on Trent, although an SOS is £17.80 to Liverpool Stns. I'm not sure if one should compare SOS with SDS, but I think it's reasonable to conclude that Stoke on Trent isn't an appropriate routeing point. In any case, one would probably end up doubling back between Stoke and Kidsgrove.
- Wilmslow to Liverpool Stns route VIA CREWE is £12.20 and route VIA MANCHESTER is £13, so Wilmslow is an appropriate routeing point.
Crewe to Liverpool Group can use map EM, ML+NC, or NC+NL.
Stockport to Liverpool Group can use map LY, PS, or TP.
Wilmslow Group to Liverpool Group can use map LY or PS.
Choosing Crewe as the routeing point, on map EM you can go from Poynton to Kidsgrove to Crewe and on to Runcorn, Hunts Cross, and Liverpool.
Choosing Stockport as the routeing point, on map LY you can go to Manchester, Earlestown, and Liverpool. You can also go via Manchester and Warrington on map TP.
So yes, both of those journeys are valid.

And I should mention our standing advice on monthly season tickets: don't buy them! You're allowed to buy a season ticket for any period you like between a month and a year, so it's a good idea to plan your purchase so that you miss out paying for some weekends or leave periods. You can also buy more in advance now if you want to get it at the old prices.
For example, if you needed a ticket to start on Monday the 23rd of January, buying a 1-month ticket would get it up to Wednesday the 22nd of February and cost £268.80 (23 working days, £11.69 per day). If instead you got the ticket valid up to Friday the 24th, it would cost £287.00 (25 working days, £11.48 per day). Not a huge saving, but better in your pocket, right?
