It's hard to block all shipments, but those that come through get purchased with a heavy markup. I didn't heard of these companies, but in consumer electronics I can still buy a lot of stuff from companies that aren't working in Russia, but it would not only cost me an arm and a leg since ruble is a rubble right now, it would also mean additional costs from gray importers like in this article and our store chains compensating their losses by putting them onto consumers. A lot of money go to the middlemen and corruptioners, supporting their practices, so it's probably not bad I guess.
