It doesn't die?

Are you sure it runs?  ie, does the root crontab have the proper path elements for this to function?

Check the return code from print.  As in:

sub writetemp {
     open (NEWFILE, ">/tmp/$0.count") or die $!;
     my $ok = print NEWFILE "$product{name}.value $product{value} $date";
     if ( ! $ok ) {
        print STDERR "error on print to file:  $!\n";
     }
     close (NEWFILE);
}

or print NEWFILE "$product{name}.value $product{value} $date" or warn "$!";


You may also set $| (autoflush) to true in case there's some weirdness in output buffering.
Shouldn't be but ...
