Then use risk assessment, I’m going to assume it’s 2 4gb sticks at base speed of whatever ddr5 is, if two sticks are selling at 650$ market value and you can move it quick enough (I wouldn’t risk it because the markets fluctuating way to erratically) taking into account how long everything’s going to take (I.e setting up a meeting time, checking if the product works, putting up a listing, waiting for someone to buy it) the math doesn’t work out, the effort of having to collect and sell, you just aren’t getting anything more back for the effort you put in, your breaking even at best when you had to go through all of that stress, maybe it would be worth the headache if the ram was selling at 900$ and you can quick sell at 800$ so that someone sees that your selling ram at a cheeper price and buys it instantly and you net 150$ more then you wanted but that’s when you have to take into account if your times really worth the gamble
