En route

For items that are "en route" (rental movies, library items, packages to be mailed or dry cleaning), put a basket or a crate by the door. When you're ready to run errands, simply put the crate in the car. It'll keep your stuff looking neat - and you won't have to pay late fees for the DVD that disappeared under the seat. For library items you might want to go a set further. It's a nice idea to put a sticky note on the item indicating the last day you can return it without a fee.
