You can put items in more than one cart.

If you have a recurring item you want to add, there are several
ways. I believe an [add-item ...] tag is floating around somewhere,
and it can be done easily with:

	[calc]
		$Carts->{recurring} ||= [];
		my $item = {
				## required attributes
				code => 'RECUR-01',
				quantity => 1,
				## optional attribute
				attribute => 'foo',
			   };
		push @{$Carts->{recurring}}, $item;
		return;
	[/calc]

Now you can display it with:

	[item-list cart=recurring]

		[item-code] -- [item-description]
		Price: [item-price]
	[/item-list]

and total it with:

	[total-cost cart=recurring]

This is all independent of the main cart.
