Where can I find legitimate discount for Topaz products?
I've always found a good source for valid discount codes is YouTube. Look for anyone who is doing videos about the product you are interested in and see if they give you a discount code in the description, (usually between 10 & 20%)
Try Jim Nix on Youtube, he has a discount code for 15% which I think is still valid
Anthony Morganti has a 15% discount code for Topaz. Here is the link- you need to scroll down the page until you get to Topaz: https://onlinephotographytraining.com/save-money/ He also has codes for other products and does a lot of helpful videos on YouTube.
