A resource for obtaining copies of death certificates for ancestors who died in the state of Georgia, USA is Georgia Virtual Vault:
http://content.sos.state.ga.us/cdm4/gadeaths.php
The feature I like best the one that gives you every occurrence where the name you enter appears within the index [I found an ancestor because she was the informant on another ancestor's death certificate]. Be sure to use the
'Advanced Search' option for the most results.
The site allows you access to photos of death certificates with transcriptions of the certificates, and access to many other records [such as property tax lists, Revolutionary War records, land deeds, etc.]
