Would love to see more stores “linked” to DD like the Steam store is too Auto-add games to collection. Regardless, you guys rule! Thank you!

Definitely! Just as Switch games show eshop and various stores for physical prices, PC should show more than one PC store. Steam might be dominant in the market but there’s nothing “official” about it that means it should be the only store tracked.
My suggestion is that the Steam icon on the main page should be changed to “PC” and then games should show prices for all PC stores they appear on. I do not use Steam at all, but I use GOG a lot and would buy my GOG games using the affiliate links here if I had the option.
