I have done most of these and will continue to do so! I will caution folks when flipping, be careful if you’re using eBay to sell the higher end items. Their final value fees add up quickly and are not taken out immediately. If you don’t plan for them at the end of the month, and you’ve sold a lot $$ wise, they can get you.
Poshmark and Mercari are great places to sell higher end clothing items and accessories. They take out their cut immediately, and the cost of shipping, so what ends up in your account is all yours.
In a real bind, plasma donation is a possibility for some people as well. As I have medical issues, I’m not a candidate, but most younger people are.
Thanks as always for sharing Brian.
