In most cases you don't have to pay more than zero anyway, I'd only pay more in cases I see justified (e.g. late port cause it's the first time it's releasing so it hasn't had the chance deprecate in value). Usually you can just wait a bit and they'll drop in price anyway.
L.A. Noire Remastered for Switch for example is now £20 same price as on PS4 and Xbox One:
