A few months ago I'd be more likely to boycott Russia and praise Georgia for its economic reform efforts, but what it did on August 7th changes everything completely!
Most people have probably never bought anything made in the nation of Sakartvelo (aka Georgia), a possible exception being their main agricultural exports: tea and especially wine. Note what their alphabet looks like and avoid it on all products. When buying European wine, check to make sure it is not from Georgia. If you see a wine store carrying Georgian wine, please let them know that this country has conducted repression and war crimes against its own civilians!
If you know other companies associated with Georgia, please post about them here. Wikipedia currently lists only four: Bank of Georgia, Georgian Airways, TBC Bank, and Wissol Petroleum Georgia.
This idea isn't fully baked yet, but it has to start with something...
