Instructions:Seatwave is a peer to peer ticket exchange, where fans can sell tickets to other fans if they are unable to go for the concert. They also offer insurance protection in case the show is canceled, and you are guaranteed to get genuine tickets because they only release the money to the seller after the event has taken place.
Anyways, they have a 10% off code for any ticket purchases this week, which might come in useful for anyone looking to get tickets for music gigs, sport events, or theatre shows.
I myself don't support ticket touting, but if you really need tickets for an event, Seatwave and Viagogo are the two biggest ticket exchanges and most reputable. So don't vote cold because you're against touts; vote cold/hot based on the deal itself, which is a rare 10% off voucher from Seatwave!
Edit: It should work with quidco too! Nothing in the quidco Terms and Condition about using voucher codes, so that would probably mean 10% off from the voucher, plus another 10% from quidco! (making around 19% discount).
