Once you get up there in the higher levels the gold the trainer sets is not enough to buy anything. I was wondering if instead of making the trainer add a fix rate of gold to your character you could instead make the trainer add that number of gold each time you press the button.
Right now the base is 999,999 which one would think is enough. When you run out of money and press the button it resets that number to 999,999, making affording those better items at later levels nearly impossible.
thanks for the video. it appears that those items aren't purchaseable because of some other requirement not being met (the areas listed in RED). sometimes you haven't met a strength requirement or the like. it appears in the video that all of those items were below 999,999 in cost.
