Do you perhaps want fast lookups of the prices?

Yes, exactly. This actually a rewrite of another script. The orginal programmer used a long series of if/elsif statements. This is how I cleaned it up.

This way, there's no need to store two versions of the key.

The real problem comes like this:

use CGI qw(:standard);
my $input_item = param('item') || 0;
my $subtotal;
my $item_name;
if(exists $ITEMS{$input_item}) {
   $subtotal = $input_item;
   $item_name = $ITEMS{$input_item};
}

I wanted to explore how Perl's closures can be manipulated, and ended up creating an object system by accident.
