Displaying Savings

Hello,

In an attempt to be similar to amazon.com in the good parts and different
than amazon on the bad parts I have written a couple of GlobalSubs to
display your savings on an item.  I have a price field, and a retail field.
The retail field holds a higher value than the price field.

This sub returns your savings in the format of $4.99 ...

GlobalSub <<EndOfSub
sub you_save_dollars {
my($retail, $price) = @_;
my($yousave);
$yousave = $retail-$price;
currency($yousave);
return $yousave;
}
EndOfSub

Here's the minivend code in the page to return the value:
$[currency][perl arg=sub interpolate=1] you_save_dollars ([item-field
retail], [item-field price])[/perl][/currency]

This sub returns your savings in the format of 20% ...

GlobalSub <<EndOfSub
sub you_save_percent {
my($retail, $price) = @_;
my($yousave);
$yousave = (1-($price/$retail))*100;
$yousave = int($yousave);
$yousave .= "\%";
return $yousave;
}
EndOfSub

Here's the minivend code in the page to return the value:
([perl arg=sub interpolate=1] you_save_percent ([item-field retail],
[item-field price])[/perl])

I'm wondering if this can be added as a 'normal' minivend tag.  something
that can be accessed with [item-you_save_dollars] and
[item-you_save_percent].

Any ideas?  Mike, are you interested in having this in the features set?
