This is the way, but also, places like eBay are increasingly “professionalized” by huge resellers and refurbishers who squeeze out any possible margin. I’ve also noticed that thrift and consignment stores aren’t such a bargain anymore. You can often get a better deal from large retailers when they go on clearance.

P2P transactions still pay off but it’s not as easy as it used to be.

That's good to know regarding ebay. I don't use it much, but I wasn't aware. Agreed with regard to thrift stores. Some of them have seen quite a lot of inflation. I think it's yard sales and minimalism for me.
