A rotating "on sale" tab is actually a great idea. If four different items were offered at a lower rate than usual I'd think most people would respond well and be more inclined to spend units in the store more often. I know I'd buy more revives, at say 25 units a pop for example, if they popped up in the sale tab rather than rebuilding the inventory over time when I get low. Hopefully this is something we'll start to see instead of what the sale tab currently is.
I wouldn't be opposed to that. I have suggested in the past about a set schedule for the Energy Bundle each month. It comes in handy.
