I had the same thing..
Few years ago bought the wife a food processor for xmas, i know, im a charmer, she did ask for it though.
Anyway, ordered one from argos for about £50, 2 identical ones came in one larger box.
Turns out, they are delivered to argos in 2's which are supposed to be split then but somebody just picked the box before and sent it.
Sold the other one
