>Something common is people trading.
People can trade their good condition diapers for a larger size, or another brand that worked better. Sometimes people trade new items they bought that didn’t work out for them.
Sometimes it actually reminds me more of bartering. For example, someone who makes diaper detergent might send some to a mom who makes stuffed animals, in exchange for a handmade gift for her child.
Unfortunately I can’t think of anything to offer up right now, but it sounds like the perfect solution for me. I need so many things like pail liners, wet bags etc. I’m not picky about what they are or what they look like as long as they work for me.
I’m trying to only spend our money on the most important things that just can’t wait, and of course, that is diapers right now!
Like anything though, trade at your own risk & make sure to check out the person’s reputation and trading history, ask detailed questions and for detailed photos of the items and make sure all parties understand all terms of the trade!
