As title, basic ring binder for 50p. Picked up in Newmarket St Asda in Falkirk. No reduced / to clear stickers, it's just that cheap! They had another one similar on shelf for £1. After stupidly paying £2 for one at Staples (only difference was colour), this is the cheapest I've seen in a while.
Have included barcode, will try to upload receipt in comments
