What other people are doing with their money isn’t any of your business. However all the help you did for others is an awesome thing. Seriously though, this kind of thing shouldn’t be making you lose sleep over it. If your really not losing sleep over it then it’s not a big deal as you make it out to be. If someone is willing to pay top dollar for an item then so be it. Lol. Not sure why you’re literally screaming over it. But good job on you commitment to helping others so here’s a cookie :)
