So I've been playing the game for a while, but every time I fill up stocks in the stores, they stay exactly the same whether I'm playing it or not. The only money I get is by the quick sell option, shipping people to random floors, and filling up stocks in new stores. How can I actually make money by not really doing anything like most people?
I play TT Now and again and the only thing I can think is that your staff don't have enough skill. Try to have people in their "dream job" or at least the correct field ( same colour ) . Not only does this reduce the cost of stock ( from memory, I don't have it installed right now ) by a max of 27% (9 for each staff that is 9 in that colour) but I believe it also increases their selling rate.
