Am I over paying? International food aisle

Well today I learned Tesco is cheaper than Sainsbury's. 500ml here in Sainsbury's is £1.90 which is $2.43. But I think it's because they're targeting those on the meal deals, as 2 litres is only £1.25.

Only slightly - Tesco over here has that 500ml bottle at £1.25 as Brucey says, which is apparently $1.61 according to google (Our £1.25 price includes the tax as well though)

£1.25 for Irn Bru where i am, so that's quite reasonable
