How much is $1 worth in grass

need to work out how much a $12 upgrade is worth

 

64 grass is the average so the 12$ is around 12 stacks of grass but to make it a higher chance to get upgraded add another few stacks ^^

 

wait, are you buying somebody one?

 

I was not anymore. but will do upgrades in the future

 

If you have Negotiation 100 then you might be able to talk them up to like 65:$1.
