Humble Bundle offer Vegas and DVD Architect for about $25

Humble Bundle is a website that sells software at amazingly good prices for charity. They has Vegas 15 available on the site for a suggested donation of $25. You also get a selection of other Magix programs like Sound Forge and DVD Architect in the bundle.

This gives you a totally pukka version of these programs with a permanent licence. Magix donate the software because it is for charity and they hope it will make you update to the latest versions.
Vegas is not my favourite editing program but is actually very powerful, however, the real interest here might be the fact that you can get DVD Architect cheap. This may particularly interest Adobe CC users who cannot get Encore any more and need to look for an alternative.

The offer lasts for the next 13 days.
