Came across this as $0.95. I hope this game becomes cheaper for Switch (not in eshop).
The Stardew Valley Collector’s Edition will include a disc version of the game and a copy of it's soothing soundtrack, as well as two physical goodies: a “condensed mini version” of Kari Fry’s gorgeous Stardew Valley Guidebook, and a map of Pelican Town.
