โโโBE AWARE OF VIAGOGO ETC. They have very bad reputation โโโ
Maybe it is different with the country, but I do not think so. In Czech eg. there are a lot of complaints and litigation (as usual with no ending fight and loosing money). They have very bad reputation for sending copied tickets, sending tickets days before events etc. Everything depends to the end seller, who is anonimized. And the worst thing, it helps people reseling tickets, although they took them from general official seller (without no plan to go there, just to earn on that). There they are sold out for this reasons too ๐
