Its customary for brands to put up their signs ahead of time so they are visible long before the promotions and campaigns begin. In marketing, promotional teams look at specific periods on the calendar when starting their seasonal sales, grand openings, or open houses. The “teaser event” usually takes place about two weeks or more, with signs being put up to introduce the promotion with minimal information. You can start putting up signs and posters for the sale with all the information and deals you want to show seven days before your event or the start of your sale. The last three days are the “countdown days,” where promotions and signs are ramped up. Once “D-day” hits, you start the sale with a “kickoff” and let the signs do the talking for your campaign.
