If you haven't gotten rid of everything yet, one thing you can do is have a party where you invite friends over to take stuff. I did it and called it a "house colding party" because we Americans call it a "house warming party" when you move into a new place and friends bring gifts for your new house.

I'm proud of you for doing this thing!

Nice fins! I have some high end dive fins, too. I'm glad i kept them. I'd forgotten how expensive they can be until I was looking online the other day to find some to have a spare pair for friends and wow! Like $350 usd!
