What is available from where differs depending on where you live. According to the official Vancouver 2010 website, there are different outlets to buy tickets from depending on your country of origin. For instance, US citizens are not allowed to buy tickets from the official Canadian distributor. That official website has a list of what vendors or websites offer tickets to their citizens.
For instance, just a simple check on my official distributor’s website showed Snowboarding tickets as still available. Prices for one Snowboarding event ticket, a ticket to another event of your choice, admission to the Victory Ceremony and a Hospitality Pass ranged anywhere between $1202-$1523. Check your official distributor, as listed on the Vancouver website, and see what you can find.
