Python program that calculates the final price of an item after asking the user if there is an in-store discount and if they have a coupon.

Item calculator

# module calculate_store_discount() is where I am having issues. I also tried linking original_price()
# to calculate_store_discount() so I wouldn't have to have the user re-enter. The in_store_discount() 
# and calculate_store_discount() are going to be 'duplicated' with variables relating to the 
# coupon inputs and calculation ( calculate_coupon(), coupon_discount() ). Another module is going to 
# be created to calculate the final price after I figure out what my hang up is with the math.

    store_discount = in_store_discount()


def welcome_message():

    print  "Hello! Calculate the final price of an item with an in-store sale and "
    print  "a coupon if they are available. First input the original price (ex. 1.00) "
    print  " follwed by the in-store discount (ex. .20), and the coupon amount. "
