Was in LIDL yesterday in Belfast and I picked up a 21 pack of Walkers crisps for only 99p! 7 Salt & Vinigar, 7 Cheese & Onion, & 7 Ready Salted.
Thought they must be out of date, but not until the end of October. Asked the guy at checkout if it was Nationwide, he said yes but I'm not sure - not sure when it ends either, the 2 semi skimmed milk for £1.09 ends on the 13th so it may be the same.
They also have Goodfellas delicia pepperoni, loaded cheese, and deep pan pepperoni on a 2 for £3.00 offer...didn't see if anybody posted yet :)
