Regarding Soph & Lauren's points, secondhand wands are totally a thing and I imagine Ollivander's would have some that are available at a discount. These would be like "certified used" electronics in these days, where they've been tested to make sure they're still working properly- no dead cores or cracked woods, no weird side effects. And then if you go get a used wand elsewhere it's more of a mixed bag and you don't know whether it'll work well or how long it'll work.

I'm very interested in Jimmy/Billie if Finn is down! And I'd love to backdate a thread for Meri if you tell me when Dante, lmk if you want Yuri at Ollivander's (to buy or attempt to steal, lol) or elsewhere
