Update Humane Labs to Sell chemicals by stacks of 10

[Dirty Mike]

Still keep being able to purchase each chemical individually but under each one have a stack of 10 for $1000 

save our mouses a few thousands clicks

This would be a time saver especially when you go to buy them in large amounts

+1 

[Straza]

Huge +1 or something like stacks of 25, 50 etc

+1, great suggestion, but I believe being able to choose the amount you want to buy at one time would be much easier.
