Check somewhere else before Steam, especially with The Witcher games, as places like GoG or Amazon have them without DRM.

I live in Brazil, where a new game can easily cost more than a hundred dollars. 2 months ago, I got into Steam and saw they convert their prices to our currency, which is absolutely amazing. Otherwise I would prefer no DRM physical copies.
