A similar timing error often takes place with e-mail. Many merchants believe that e-mail should arrive on the first morning of a 1 or 2-day special to encourage impulse buying, but that fails to discount the brick & mortar aspect of retail. A customer still needs to drive to a store and therefore must plan time to drive to the store.
Learning: If you are going to communicate a short-term offer or sale at a store, time it so it arrives in home at least a full day before the sale starts. With e-mail, you can be precise with timing but it is not as easy with snail mail.
