Be Careful... buying from Seatwave is not risk free.
I purchased my tickets for Monty Python as a birthday present/treat for my partner and the tickets arrived as promised and looked genuine. We traveled by train to the O2 and having got to the front of the admittance queue, our tickets were scanned and we were told that they had been voided and we weren't allowed in. The supervisor at the O2 said that our tickets were actually still for sale on the stubhub website.
Long story short. Seatwave refunded the cost of the tickets but we are still out of pocket (train), didn't get to see the show and had a fairly miserable birthday evening.
Very poor Seatwave, I will never use Seatwave again and would strongly suggest you don't risk using them.
