Here's one way of doing it...

{php}
$foo = $this->get_template_vars( 'product' );
$bar = $foo['product'];
$woof = $foo['productcode'];
 
echo "<br />";
echo "$bar";
echo "<br />";
echo "$woof";
echo "<br /><br />";
 
$findme  = 'Cheap';
$look = strpos($bar, $findme);
 
if ($look == false) { 
 echo "The string '$findme' was not found in the string '$bar'"; 
} else { 
 echo "The string '$findme' was found in the string '$bar'"; 
 echo " and exists at position $look";
} 
{/php}

There's probably an easier way using smarty alone, I'll keep looking...
