Got right answer. Whats the right way to work this?

[tlp]

Eric purchased four tires through the Internet. He paid $62.30 Plus $6.20 s&h per tire.
There was no sales tax on this purchase. When he recieved the tires, Eric had to pay
$8.00 per tire for mounting and balancing. At a local tire store, his total cost for the four
tires with mounting and balancing would have been $425 plus 8% sales tax. How much did
Eric save by purchasing the tires through the Internet?
(The answer is $153. Just want to make sure I worked it right.)

($62.30+$6.20+$8.00)*4=$306.00
$425.00+8%
$425.00*.08=$34.00
$425.00+$34.00=$459.00
$459.00-$306.00=153.00
