Not sure if this is nationwide, but if it is, it is likely to start tomorrow (Sunday 30th)
There were a big stack of these at Aldi in Bury (Crostons Park). No price displayed so I asked a member of staff and he said £1.99.
Took four packs to the till and luckily it was the same chap who gave me the price. Turns out that price is starting tomorrow but he honoured it for me today.
