Big official stand of Stabilo products all at half price (fineliners, highlighters, pencils etc).
As for these pens: originally £4, now £2. Going for £6.59 on Amazon.... nice pens for a couple quid.
Dunno if local deal (seen at Cardiff Excelsior Avenue) or whether National - anyone with details please update this description as appropriate!
EDIT: looks like it's Nationwide
