k so by no means am i a expert or anything but i do have a tip for people:
k do not only go for the high priced items they will sometimes get more money than others but personally i feel that if you can but several smaller items worth a few hundred and make a 50$ profit or so it is worth it even if it doesnt get you as much money also it gives you experience in the market so you have a better understanding of it. also if you have a item up for sale and it doesnt sell in 3 days or earlier the general rule is that it is priced too high that is not always the case.
k so theres my tip if you ever have questions pm me
