Where to get snacks like this in Poland?

Sorta dumb question, but I’m from California and am hoping to find Polish substitutes for some of my comfort foods back home. I’m not too picky, just looking for anything similar or any other recommendations.

Of the products mentioned here, I’ve only managed to find Canada Dry ginger ale in Biedronka before, but not the sugar free version.
