Want to start collecting manga, love haikyuu and trying to buy it for $350 or under (I’m a kid using my moms account) anyone selling?

haikyuu is one of my all time favorite anime’s and I’ve been wanting to start collecting for a bit. I’m 12, so I don’t rlly have a lot of money. if anyone is willing to sell for $280-350 I would be rlly happy. other mangas I’ve been wanting are Vinland saga deluxe edition (i already have the first 2 but want the rest), and aot. Also, I’m buying horimiya 1-5, 7, and 9-12 from someone so if anyone has the rest of it to complete the series I’d be rlly grateful
