Continue? (y/n): n
===============================================================
Bye!
Specifications:
Use the following table to calculate shipping cost:
Cost of Items Shipping Cost
< $30.00 $5.95
$30.00 - $49.99 $7.95
$50.00 - $74.99 $9.95
> $75.00 Free
• If the user enters a number that’s less than zero, display an error message and give the user a chance to enter the number again.
