No no no, they have it all wrong.
90 pounds Sterling is what they are referencing. No that is about $120.
However you need to remember that cheese is a lot more expensive over there than it is here. 90 pounds (sterling) is about one frozen pizzas worth of cheese. And we all know on average Americans eat one frozen pizza a day.
Thank you space trooper. I knew I knew the bug but couldn’t place it right away.
