With 50, 000$ I would refund my credit cards 1000$ and 300$.
I would maybe buy a house, well 50, 000$ seem a lot, but a house cost a lot more.
I would buy a new fridge, stove, washing machine and dryer that are for limited space. No not a small one but those like tower.
I freezer, brand new custom made computers, some good quality furniture for the living room and bed rooms. A lot of clothing because i don't really spend money on clothing ^^
Many commission from artist that I like, place maybe like 40, 000$ in the bank to gain money with it. Give food to food banks, good food, not cheap stuff from the dollar stores.
I would commission for a custom made 4 or 5 foot tall anthro plush from maybe a fursuiter who do great job.
I might refund my bro of the money from the heritage that we use, but then again he was never close to us and we don't have contact with him. Maybe my dad will suddenly find interest in us if we have money? but I would push him away since he was never there for us as kids and today we barely see him 5 minutes a month.
