Okay, so this deal might not be clear-cut enough for everyone but the way I see it is that there is easily enough to be saved for me to put the deal out there...
So you can presently get a NUS Extra Card as a graduate seemingly without limits. More details are contained in the thread here, for which thanks go to Qaari:http://www.hotukdeals.com/deals/nus-extra-card-for-graduates-9-99-endsleigh-1960179
Now the deal-maker is that you can use the NUS Extra Card with a Unirider from Stagecoach. In the first comment, I have posted an email exchange with Manchester's Stagecoach enquiries confirming the same.
This means that you can potentially get a year's worth of bus travel for in the region of £200* (£10.00 for the NUS Extra Card and £190.00 for the Unirider across Manchester, for example).
* The price of the Unirider does seem to vary based on location, and I'm not sure that the year's Unirider is available everywhere yet. I only know the Manchester area so will leave it to people to comment on their local area if they can. If not on sale already, I would imagine that the year's Unirider for that area would go on sale soon.
When I ordered mine I had to select 'Other' as my institution. If your NUS Extra Card hasn't arrived yet, you can simply let Stagecoach know this and can still proceed with your order. All in all, I came across no problems when ordering.
The Manchester Unirider runs from 1st September 2014 to 30 June 2015. That's 43 weeks. If you were to buy a standard Megarider at £13/week for that time it would cost £559.00, so a Unirider would save you £359.00 over the year. As I said, the figures vary across the various regions, but I'm sure that it would be a similar sort of saving that's possible.
This was very straight-forward for me. If you have any questions, please let me know!
Just to confirm, I used a NUS Extra Card for 2 years prior to posting this deal without a single issue whatsoever.
