In recent weeks, Tango Apple.
In Iceland, you can see the section of the shelf that says "Tango Apple, £1.25" per 2L bottle, but that section has been empty for the last few weeks now. May as well just take the sign down and fill it with a different product? Also, if I order online from Asda, it's no longer available on delivery day so it gets subbed for something else. It's a bugger because I really like that drink.
