I just came across the bargain of the week! All the Nik Plugins from new owners Google for $149, with another 15% off from the bottom of this link to Northlight:
I just picked up the whole suite for just over $126 the lot, but offer seems only valid to end of Easter, so hurry if you want them. I was struggling to come up with the $499 for the original price, but very happy to grab them under this deal.
Here is the link to Nik:
