Translation (3rd link in the first post): "From 4 to 6 April 2011 Groupon subscribers are able to get a free promo code that can be exchanged on this page until May 3, 2011 for an activation code for Kaspersky Internet Security 2011 to protect 2 PCs for 3 months. Activate the resulting code before August 31, 2011." So you have until tomorrow to get a code from the Russian site. The license also works with the English version of KIS. Groupon will send you a daily mail on the address you provide.
