Only realised earlier this afternoon too. Had a look, and decided to go for something a bit different. Managed to get front row Dugout tickets, edge of the penalty area, for £40 each which I think is a great price. It doesn't include the usual free food, but you do get a drink and a programme.
Even the Chemistry lounge was only £70, before it sold out.
Great chance for people to experience the hospitality lounges at reasonable prices.
