I was in my local Tesco today, and noticed the 2 1.3kg tins for £10 has finished, though noticed 1 sel still advertising the deal on Roses.
So grabbed 2 tins (not being greedy) and they went through at £7.99 each = £15.98.
Went to customer service desk, and they honored their double the difference policy. Hence i was given £11.96 back for being overcharged.
Making this £2.01 a tin.
I wouldn't normally post these overcharges as seperate deals, but these tins have been placed all other the store in different places, and it's highly likely many other stores would have missed removing a ticket or 2.
So keep your eyes when next in Tesco, and if you see a sel with the offer on, grab yourself 2 tins for £2.01 each.
