[ic] No shipping for dealers?

[Peter N.]

Greetings,

I have the following code which makes it so that there is no sales tax 
for dealer accounts.  Can I do something similar so that shipping is 
also not charged for dealer accounts?  I tried adding

$Config->{Shipping} = ' ';

but it didn't have the desired effect (or any, for that matter).

Thank you,

Peter
