If you want the key that corresponds the the lowest value of a hash, instead of code like 
my $lowest = min values $products_and_prices;

[download]
you'll want something like 
my ($lowest) = sort {$products_and_prices->{$a} <=> $products_and_pric
+es->{$b}} keys $products_and_prices;

The parentheses create list context on the assignment, so that lowest gets assigned to the first list element, which is the item that was smallest. Of course, you could write something more efficient, and I haven't tested the above because you still haven't posted useful example code.
