Seems to be national as seen this is several ASDA stores, kids of their paint is reduced, actually lots of their DIY stuff is reduced but the paint seemed exceptionally cheap! interior and wood paint. Cheapest was £3 but also had others reduced to £5 and £8. Same thing in dulux would be pushing £30! So I know you might need to put on an extra coat or two but when it's that much cheaper it's worth it in my opinion.
Had some nice colours as well, mix of silk and Matt.
Saw this is Asda hollinbury in Brighton
