Just an easy way to get additional candle stock

Put down 4 candle stations (3 additional ones)
Your sims need to use them and restock them simultaneously
This should give the other 3 candle stations 2 additional candle stocks
At the end your first candle station will have 2 candle stocks and the other 3 will have 1 candle stock each
