Hardly!

You are welcome. I occurs to me that the shipping selector might still 
return the shipping method, but with $0.00 as the cost, because the 
criteria (weight) will still be within the scope of the method. I don't 
recall if [shipping ...] omits methods on out-of-range, returning zero, or 
both. Also, another way to handle this might be a usertag (the following is 
untested):

UserTag noshipping Order limit cost
UserTag noshipping Routine <<EOR
sub {
         my ($limit, $cost) = @_;
         my $current = Vend::Interpolate::subtotal();
         $current += Vend::Interpolate::salestax();
         if ( $current >= $limit ) {
                 $cost = 0;
         }
         return $cost;
}
EOR

Then each entry of your shipping method would look something like:

SHIP1   Shipping method 1       weight  0       9999    f [noshipping 
limit=28 cost=0.98]

Again, I'm not sure whether or not the selector on the checkout page will 
suppress the $0.00 cost.
