Centralsports - Asics runners from $46.53 (plus postage)
For example, you can get the Gel Blackhawk (a decent general shoe) for $85
Boys/girls runners - can be had for $49
And yes they have New Balance, Adidas and even (if you're that way inclined) Nike.
Even better, you can take a further 5% off the prices above by using a code that can be got from the Infiniterewards site mentioned in a previous post - so those $49 shoes cost $46.53.
