3rd Level Factories

Level 3 factories are very profitable but hard to keep alive buildings. 
Chain
This is because if you are a chain kind of player, you must have at least two buildings from the level 2 to maintain this level 3 factory, just because each factory can make ~12 goods per hour so for the level 3 you will only make 6 goods each hour. To prevent this having two buildings to support the level 3 will be much better and your factory will run much more smoothly.
Non-Chain
In other way, some players don't like chains so they buy goods from the market to maintain this level of factory. This is actually more difficult since you won't find all types of products in the market at all times, specially when you most need them. So for this will require the player to be more active.
== What's better, market/bank or shops sells? ==
Players who make their own level 3 products sell them on their shops, this is a good technique because you get a bonus for each good you sell in shops. But sometimes you don't have space for another building and still you want to make a level 3 factory, then in this case, obviously a wise choice is to sell them in the market.
Tip:
 You don't always sell all your level 3 goods you produce on shops so you might have a few extra goods that you can sell in the market for
 market bonus.
