Just a word of warning.
I heard from the branch that over the last few games, people have bought tickets via Go Go (never heard of it)
Anyway, the tickets being sold on that site, are Children tickets being bought from Russia, and then sold as adult tickets.
A few people were stopped going into the Cardiff game because of it, and it seems a good few have been bought for Munster match this way too.
I'd recommend avoiding buying any tickets off any non Connacht official sites
