I think those savings are the most difficult for us to assess right now, because if you're not delivering a product every day, is there a risk that people will not use it? Look in particular at our $1.2-billion marketing mail business. If you are having a sale on the weekend at your store, you want your marketing message to be in the mailbox by Thursday or Friday. All of those implications for small businesses or large retailers are very important, so it is an area of complex understanding not just from the mailer's perspective but from an operational perspective. If we deliver parcels every day and there's a separation of streams, that will add more operational complexity. This is an area that needs a lot more work.
