There's a lot to unpack here.
Remember Sanity, the CD and DVD store you bought trashy singles from after seeing something on Video Hits or RAGE? Well, they're still around. The company still has a lot of stores in regional areas — places where rents are cheaper and there's less competition from JB Hi-Fi, basically — and they've expanded into more merchandise, books, and even video games. (Their website even looks like the front of an EB Games store, but anyway.)
But for some reason, I'm not really seeing Sanity as a video game retailer. I wonder wh—
Even for Sanity, which doesn't compete that strongly in the gaming department — they're still selling Just Dance 2017 for the Wii U for $80 bucks, and for whatever reason, COD: Advanced Warfare on the PS3 for $100, as well as plenty of new releases for $99 — this is a bit far.
Sanity's Switch stuff is expensive, sure. But there's not much beyond the odd bit of hardware (like $120-plus for a Switch dock), so there's a 1000% chance that this is meant to be $99.99 for a new Switch game, and not $1000. People are keen for a new Castlevania, but not that keen.
$100 is still way too much for any Switch game, mind you, but at least Sanity is still around to give some high schoolers a job or two. As for Bloodstained, you can get it on PC for $52 and for a much more equitable $69 on the Switch so ... maybe do that instead.
