In the aspect of openness I wanted you all to see my highest and lowest sales of the past 90 days, The highest ones were good finds as well as niche research which allowed me to sell them for these prices and make great money, the other 4 were worst finds or ones that have sat in my inventory that long that I let it sell cheap
I aim to have no item in my store older than 6 months so if an item is past that or approaching that point I allow it to sell cheap enough that I can use the sale to just cover the cost and find a new better item. I also take the time to learn what items are stagnant, and that I should avoid buying or over buying in the future
