Not sure if this has already been mentioned but the PlusBus add on is only £1 in June, apart from for a few selected towns. Also strangely the PlusBus website says some TOCs websites are not offering the extra discount, including East Coast.
There are just two places in the country that I could justify buying a PlusBus ticket for.
Blackpool, Maidenhead, Newbury, Newport, Reading and Swindon...
...are they all predominantly served by a local company, e.g. Reading Buses, or is it me? I know that some - Swindon for instance - have at least some major company service (Stagecoach), but on a local level and not inter-urban?

Hmm, let's see:
Reading - Reading Buses
Newbury - Newbury Buses
Swindon - Thamesdown
Newport - Newport Bus
Blackpool - Blackpool Transport
Maidenhead - ? (Anyone know an arms length company?)
So I guess your assumption seems to make sense.![]()
