Yes, I have noticed the LFS in my area aren't as crowded or busy. We even had one close down recently. I have also noticed a lot of whole tank setups for sale on facebook marketplace. If I were someone starting to get into the hobby, you can get a really good deal on marketplace.
Edit - Its hard for me to judge before the pandemic so I don't know the trends. I really got serious about saltwater in 2019 shortly before the pandemic happened. I get jealous when I hear all the prices people paid before covid. At least I got my yellow tang right before the Hawaii ban. Prices seem to be coming down now compared to a couple years ago.
