Some Tips

Some tips:
every customer has their own spending limit for each individual deal, and they want to spend about 60% of their limit for a requested deal.

Making different strains can be very profitable, but requires a lot of management. In the case that you have everything planned out, im pretty sure that you can make 8 bricks of an 8 mix product before needing to restock.

Dealers dont exactly care what they sell nor who their customers are. The customers determine what dealers sell if they have multiple products, otherwise if their addictiveness is maxed out then they will almost always request a deal for the day.
Dealers also do not require empty slots to break down brick products (fill all 5 slots they will not delete anything).

getting to a certain point in the game, you will feel like advancement has stopped, but it continues for a very long time if you just want to challenge yourself for how much money you can make in a day. On average before hitting a certain progression point, I would make about 80k per day from all my dealers but if I do the same thing as previously I now make 120k. (kingpin levels increase allowance and spending amount per npc by about $21)

jumping with the golden skateboard makes you move significantly faster.
hiring a botanist is a must for cocaine.
the best 3 mix for cocaine is battery, horse, mega bean.
the best 8 mix in the game requires about $6k for just mixing ingredients. (this however is for making 160 product that sells for about 1k each after up charging.)

buying multiple veeper vans for extra storage outside of properties can be a good idea (stockpiling soil or seeds)
making deals in the streets even though people have not requested it might seem like a bad idea, but the experience gain is very worth it.

if you need cash just buy some gold bars from bleuballs botique and then sell them to mick in the pawnshop (offers up to 80% more per bar) otherwise if you are super desperate for cash, smash atms and vending machines for about 30 bucks on average.
currently there is no reason to make heavenly products other than everyone will accept the deals without questioning its quality.
