> Spending $1 to make $2 is always the right decision.
Unless you have an opportunity to spend $1 and make $3. Your supply of dollar bills is still limited. It's hard to spend huge amounts of money. You've always got to consider where the greatest leverage exists.
Without knowing the ROI it's really impossible to know if this is high or not.
Spending $1 to make $2 is always the right decision.
