It's not a bad deal with:
$1 or More -- PhotoMirage & Photolemur2
Pay more than Average -- currently $14.13 -- add PaintShop Pro 2019 & CameraBag Pro
$25 or more -- Imerge Pro, ACDSee Photo Studio Ultimate 2018, & Aurora HDR 2018
PhotoMirage is sort of like an old GOTD, letting you add motion to a still image. It's a similar idea to the animated wallpaper apps, but the results are saved as videos, and you have more controls. To my knowledge Corel has not put it on sale as of yet, still listing it at $65.
Photolemur *to me* is sorta meh, but anywhere around $25 is a Very good price for PaintShop Pro 2019 -- $25 is the lowest it's been for this version, with the price low for the Ultimate version at $35, so $14 is a Great Deal.
CameraBag Pro looks like it might be useful, though not a must have, while I'd expect Imerge Pro to be very much a niche thing... Made by FX Home, it's similar to their video green screen app, but works with image files, including RAW. What will make or break this app for most I think is how good the selection tools are -- too soon for me to tell ya.
ACDSee Photo Studio Ultimate 2018 is about what you'd expect I think -- solid software but the company's never really done anything pro level that I'm aware of. Aurora HDR 2018 looks interesting at first glance, like there might be an awful lot to it above & beyond what you get with the typical Franzis HDR giveaways.
