@nova00 - you can't buy AIs. They accumulate over time as you get more and more money. On your first play through wait until you have between 100-200 then hit 'Reset' (NOT Hard Reset - that takes away all AIs you've gotten so far). After that try to wait until you have at least doubled the number of AIs you started with - and you have to spend AIs to have any chance of affording some of the later stuff in the game. Just never spend more than you started with!
Love how one of the last upgrades for the Banks is 'Friendly Staff'. After all the crazy stuff they come up with before finally thinking 'Hey - maybe we should get our staff to be friendly?' but it costs $5 quatrodecawhatever dollars!!!!
The shops operate at different speeds - Oil Companies are slow, Donut shops and hockey teams are fast. Stop asking the same f***ing question everyone else has already asked and been answered 50 times over!
