Just popped to local M&S in Tolworth and they have a few of their bottled real ales reduced. I have put the deal as National despite it being a London brewery because they also had a Cornish brew marked down.
I also got an EBA Pale Ale at 4% for £1.40
The BB date is March 2018 and the description is
Their newest ale is an American Pale Ale, generously hopped with Amarillo, Chinook, Simcoe and Citra. A great summer beer. American Pale Ale – 4.8%
I'd have bought more if I'd not cycled there!
