Leap years are rare enough that you can consider them an every four year occurrence (at least until 2100).
That makes them a good candidate for a "once every four year" promotion.
If you can't get one ready for this year, try to take notes on what others are sending out for the leap year. Are they using emails, ads, or in-store messaging? What kinds of offers are promoted?
Collect all of that and save it to look at in early 2028.
