I just gona say it now…
Don’t expect a enourmous income from your shop. Because there tons of them around, the tax, Consumable cost.
Only good point is you can change character / close your game and still have it doing some money.
Not sure how much you can do a day but it should be something close of (20-100k/ Day) depeding of where you place your shop.(Correct me if i’m wrong on that.)
If you whant fast quick afk money, Necromancer is way better (Even if some player dislike them because there 2 map taken partialy (For Dp2 and totaly for Dinabee)
Only Down Side is you have to be connected on this guy and you can’t close ToS but you can do around 100-300k / Hour
If you whant quick money grinder (Not afk) there alway warlock 2 and go to DP2 (Floor2 of Demon prison) there you farm with invocation
Income around 700K-1,2M Silver / Hour (With gem selling)
There also dungeon silver grind build (Scout3 is well know for it) and farming saalus other daily with multiple character is another way to make money.
