You can use https://gg.deals/ to see all the keyshop prices at once, and can log in with your steam and gog accounts to sync wishlists. I have bookmarked views for $5 or less, and historical lows.
You’re welcome, it simplifies things so much, and I find deals I would have missed. Note you can also filter out DRM sources so you can remove Ubisoft, EA, Epic, etc. My bookmarks only include GOG, Steam, Battle.net, Rockstar, DRM free, and Other.
