A dear friend of mine is a master seller. Whereas some people say their kids cost so much, she swears she's making a profit. Buys everything cheap on (our version of) craigslist, as soon as the kid is done with the clothes, toys, furniture, she takes good photos, makes a detailed listing and offers shipping. She has a system where she sells so much, she can tell buyers up front she does shipping on Wednesdays. In short, she gets more back on these products than she paid for.
Now, I have a box in my living room, where I toss any items I want to sell or donate. But I'm also massively burned out and I can't find the energy to do it. I've offered the box to my friend, she'll sell it all and she can keep the proceeds. I just care that it's out of my house and not in a landfill. Thank god for good friends!
