I understand your point, but I disagree. If you buy enough of these, the stable price can make a huge difference. Adding up the prices, the difference begins at box number 8. In the old system, 8 boxes cost 55,200 coins; in the new one, it costs 52,000. The difference grows quite a bit as you go on - for example, I usually buy only 10 silver boxes a day (I know, I’m a cheapskate). In the old system, this cost me 79,000 coins; in the new one it costs me 65,000. I think its safe to say that most people buy more than 10 silver boxes a day - therefore, this update lets us save a ton of gold, and get more boosting items.
