Some purchases are quite large - for example, $100 for First Aviator. I would like to be able to assign dollars from my “bank” into a “layaway” account for an item. I suspect that the program monitors dollar levels so if we are saving up, more and more $ opportunities such as chest pop up when $ are high. Basically, I’d see a new special building or an icon where I could view items available for layaway (obviously the seasonal decorations could not be included unless you had a generic “seasonal” option), selected items, and $ banked against the selected items. Dollars could not be retrieved or reallocated to other items. Thus, similar to production choices, the player lives with their choices.
