Although this would cost quite a bit more - the TfW & LNR ticket only costs about 50p more than the LNR only fare to Crewe. So you might as well buy that, and if the timings of the TfW services don't suit on the day, you can probably still bag a cheap Northern Advance.
from what I could see it isn't permitted on the super off peak but the normal off peak does allow break of journey so i think you would have to use this ticket - if the super off peak journey times are fine than this makes splitting at crewe a lot more feasible, although from what i can tell the TfW services are pretty well timed anyway
I think you're referring to the flexible tickets here. There are TFW/LNR/WMR only advance tickets on the same routes, which do ban break of journey.
What can you see, exactly? According to nre.co.uk, the restrictions for JN (the ticket code for the super off peak tickets) are:
There is no reference to break of journey, and the ticket type permits break of journey. As such, you are allowed to buy a Manchester-London super off peak ticket and start your journey in Stockport or Wilmslow.
Outward Validity: | SEE RESTRICTNS (1 day) Break of journey is not permitted |
This is another example where you need to be careful about interpreting what BR Fares is saying.
Can't seem to find it even on TFW own website?
It's a lot slower than the direct Avanti services, so it won't come up by default. You'll have to force it, e.g. by entering via Atherstone.
Or use https://www.londonnorthwesternrailway.co.uk and select "Our trains only".
Thanks. I wonder if this is an error in the underlying data. It says that a break of journey is not permitted for a type of ticket which nre.co.uk says permits breaks of journey.
I used that ticket from Stockport this week. I bought it online on the LNWR website as an e-ticket. I was concerned that, had I picked it up as a ticket on departure and the gates been manned, it would look dodgy. In the event the gate was open and it was unstaffed.
) Anyway, as the 16.33 from Crewe to Euston was cancelled we were allowed to use LNWR tickets on Avanti. I therefore reached Euston 24 minutes earlier and my hotel station (New Eltham) half an hour earlier than expected. 
Also not unusual for a late running S Wales-Manchester to turn at Crewe leaving a gap.
came up with no services available when I selected our trains only
They also turn at Wilmslow quite often too .... fine by me!

There is, but I think we're going round in circles; if you want TfW+LNR there is a ticket from Manchester to London (and vice-versa) which restricts you to TfW services between Crewe and Manchester but which costs little more than the LNR London-Crewe ticket. If you don't want to be restricted to the hourly/unreliable/busy TfW service between Crewe and Manchester then you can buy a London-Crewe ticket with LNR and get a separate ticket (maybe a short-notice advance) for the rest of the journey. Or just a standard single/return if it's cheap enough.
Given the tiny difference in price for a Manchester-London TfW+LNR ticket over a Crewe-London ticket, I'd say it's almost always going to be worthwhile buying the Manchester ticket and then 'throwing away' the Crewe-Manchester portion if need be. Obviously if you buy the Crewe-London ticket and then decide there's a TfW train that suits, you are almost certainly going to be refused the sale of an excess so you'll have to stump up for a new ticket.
