Prices vary, it will all depend on what Kind of License you want.

vBulletin (Owned License)
The owned vBulletin Forum license allows you to run the software on your site indefinitely. Along with this license, you will receive one year of free updates. Beyond the first year, you will have to pay a nominal fee, currently $30, to obtain updates for an additional year.

This will cost you £106 inc VAT, .. $160.

Or you can get the;

vBulletin (Leased License)
The leased vBulletin Forum license allows you to use the software on your site for 1 year and gives you access to products updates for that year. After 1 year, you must renew your license or remove the software from your site.

That is for $85.00.

personally I wouldn`t go with that as you`ll end up paying more if you get another license once your years up.

Wow yes that seems a little expensive. Though looking at it having to pay every year at $85 it would be worth just paying the Full $160 or so for a full license on your site.. otherwise the long run aount would be more expensive...

Totally Agree now.
