Something I have learned over the years is that is it easiest to store the smallest possible unit and then convert up.
So in this case storing pennies instead of dollars would help because you aren't dealing with decimals.
150 cents is easier to deal with than 1.5 dollars, especially when performing math operations using SQL. I am not sure how far long your application is but you should consider this an option.
