Just received an e-mail letting me know that Topaz has a 25% discount for Xmas.

I don't know if this is for "Topaz Studio" or their Pug Ins, you'll have to check.

You just need to checkout using the code: topazholiday15

I find the PS CC Plug Ins of Topaz Adjust, Topaz Detail and Topaz AI DeNoise very useful.
