Yeah, they haven't answered any e-mails, so I'm going to assume it's a mistake. Too good to be true is probably what it is.
I'm sure waytorussia.net is a fine company, but their prices for the visa are off the charts. I used gotorussia.com last time for much less. Now I was thinking of trying a Russian firm since I'm currently in Poland and there doesn't seem to be any good reason to DHL it to the US only to DHL it back to Europe.
