I am from Georgia,Tbilisi.Where I can buy that phone? I want to buy where the cheapest is, Which is best way to buy it and how?
Unfortunately you can not buy it directly from Motorola or Google, from Georgia*. Sorry I cannot suggest a specific seller; you may have to search for a reseller. But make sure that when you do find one, they are selling the version of the phone which will work best for you in Georgia.
If
this wiki is correct, the cellular networks there run on GSM 900 and 1800 and UMTS 2100. Normally I would suggest the "global" version of the Nexus 6 (XT1100), but it does not support the UMTS 2100 band; the "US" version of the Nexus 6 (XT1103) does support that all three bands listed, and
may be a better option, if you can get it. Here's a full listing of the specs of each for comparison:

If you want more specific help to finding somewhere to buy it from Georgia, you may want to make a new thread as this one is dedicated to the pictures. Many who might be able to help you find a seller might not be reading this.
*FYI to others, this is regarding Georgia the country, not the state
