I don't need endless PRs. I can review tweets, which are approved by the SEC. From Arrayit's perspective, if you're not required to issue a PR, don't do it. They are focused on rebuilding the company right now
"Skeleton" price for limited PR's is about $40 plus the companies internal costs of "handling". Many companies spend over $200 PLUS internal costs for PR's. It gets expensive if you PR regularly! Personally I also prefer "free" when the option's available! LOL
