Recently purchased 2 tickets for Chelsea - Liverpool match. Tickets on the Chelsea FC website sold out immediately. First time using a re-sale site and was nervous after reading negative reviews that appear on every site. I chose Guarantee Tickets as they appeared professional and most reviews were positive. The reservation and payment were confirmed almost immediately. E-mail queries were answered. Tickets arrived 24 hours prior to the match by registered mail as promised and were waiting for us when we checked into our hotel. Excellent service but cost tickets 4 times the face value. Would definitely recommend this site.
