Toki download code from where?

I'm currently looking for the game Toki Remake and came across some such pages. Among others, such download code price comparisons caught my eye: https://www.keyload.de/toki-download-code-kaufen-nintendo-switch

My question is: can you trust them? I once had a friend who got a download code on such a page and was fooled in the end. So money thrown out for nothing. Has an experience or what can say on which pages? Is this e.g. Good or bad?

MMOGA is okay most of the time.
