(Yesterday, 10:01 pm)Andreos1 wrote I'm sure South Bank Asda had a dedicated service until fairly recently.
Boldon Asda also had one years ago when it first opened. Can remember Olympians (presumably spare between school runs), carting around fresh air.
Yeah Boldon ASDA had 5 Free Bus Services numbered A1 to A5. 3 of the services used Double Deckers (Spectras, Olympians) whilst the other 2 used Single Deckers (mainly Leyland National Mk2).
Fun fact with Boldon ASDA free bus, is that for a school project for my GNVQ Computer Designwork in 2002/2003. I created my own version of the Boldon ASDA bus timetable based on an A4 timetable sheet I had gotten from Asda. Unfortunatley my leaflet was too good that the teacher thought it was the real thing and discarded it asking where my version was. Annoyingly I ended up failing the GNVQ course because they threw away the various leaflets I had designed on my own.
With regards to "Free Supermarket Buses" these are ones I've photoed in the North East (that I can remember). There is others like South Bank ASDA which I didn't get around to photographing or from when before I had a decent camera like the Boldon ASDA free buses.
Metrocentre ASDA had free buses running into Western Gateshead and Prudhoe. https://www.flickr.com/photos/gjm-photog...2191245664
Plus the shuttle (Cost 10p) between Metrocentre Bus Station and the Store ran by Low Fell (replaced by the S1). https://www.flickr.com/photos/gjm-photog...6562624891 and
Gateshead Tesco had one ran by Gateshead Central which ran into the underground car park (can't be many Free Shopping Buses that did that). https://www.flickr.com/photos/gjm-photog...0516325777
Consett Tesco had one running to various places, originally ran by Stanley Travel before passing to Go North East. https://www.flickr.com/photos/gjm-photog...1134936285
Bishop Auckland had two free buses from the bus station, one linking ASDA - https://www.flickr.com/photos/gjm-photog...2266028613

Some Supermarkets did have dedicated bus stops within the car parks for service buses especially when operators ran lots of minibuses that could squeeze into the car parks.
Some that are now defunct or not used are Byker ASDA, Cramlington ASDA, Benton ASDA / Hypermarket, West Monkseaton Sainsbury's, Boldon ASDA (Stagecoach used it for a little bit for the 5), Bebside ASDA, Tesco Stockton (Unless it's been used by Flex).
Anyway I've whittered on enough.
