This might be a short thread, but an important service I think. I assume it's nationwide, but went in a Morrisons near Stockport and they had 500ml bottles of ale, such as Wainwrights Gold and Pedigree for £1 a bottle as a Father's Day offer (well 5 for £5 anyway...but who would buy less than 5!). Looked a good deal to me and I can confirm that you can feel celebrated and appreciated for less than a tenner (...and I don't think you need to be a Father to get pissed on them either so it's very inclusive) Feel free to add any other offers, or just take this as my only useful retail recommendation.
And as it's international childrens day if you see any hanging around outside the beer off to treat them too
