You may not have a need for the entire collection but you can get it free if you like.
From the story on Digital Photography Review Connect
"I talked to Josh Haftel, Product Manager at Google, who told me that this new bundle is all but identical to the previously available versions, with the only changes of note being an all-in-one installer, and Google branding. He also commented that Google plans to continue to develop and support Nik software’s plugins, saying:
“We definitely plan to continue developing and evolving the software. This is our first release and by bringing this under the Google brand, we hope to show our commitment not only to Nik users, but to the photography community at large.”
If you previously bought any of these plugins, Google isn’t going to leave you in the cold for already having dropped a lot of money. If you purchased any individual plugin within the last five years, you get the entire collection for free. If you spent more than $149 on plugins since February 22nd of this year, you’ll be refunded the difference."
