The Rugby World Cup kicks off in September, but already some people are losing out.
The Consumer & Competition Protection Commission has warned against buying unofficial tickets even for face-value prices.
It's best to buy from a business where consumer laws apply, rather than a private seller where they don't and hey may not even have the ticket yet. If you do so, at least demand a photo to prove the ticket exists.
The www.rugbyworldcup.com/buyofficial website has a ticket checker to avoid counterfeits and scams and lists official providers.
