I don’t think it’s flipping if you sell a hot item every once in a while. Especially if you don’t listen to it often and you’ve owned it for a while. Then it just becomes that item’s value. But eventually those values come down. Sell while you can tbh.
Mow a lawn, babysit, give z-js, donate plasma, donate semen, pick up bottles and cans, wash cars, rub feet, be a professional cuddler, flip estate sale stuff, play poker, sell tamales outside nightclubs, steal, sell crafts on Etsy.
