Then I misunderstood, I thought you meant you could buy 3 sandwiches for €1.99, 67¢ each.
Tesco also have four choices for £1.50 each (€1.73), several 100-200g bags of crisps/tortilla chips for less than £1, and 2 litres of cola for 49p. This would be cheaper than the "Meal Deal".
Aldi-Nord often has packages with 3 in them for 2€, I was just unable to find them through the website, but I frequently see them as I often buy the 3€ salad right next to them - but they're not separately packaged if that was the misunderstanding
