Ticketmaster, a great and powerful extension if you want to sell tickets on your site.
Ease of use
Easy to setup, a lot of possibilities, the seatmap and the customisation of the tickets things we are using regulary working like a charm
As we decided to change our provider. the needed support given by the developer Robert Dam was highly valued during our migration.
Value for money
Mentioned it before, ticketmaster and its payment plug ins are certainly well worth their money.
Great extension Robert
