Saleabration (sale + celebration)

A “saleabration” or “sale-a-bration” (sale + celebration) is an event that retailers often hold featuring discounted products. “SALEabration” has been cited in print since at least 1937, with retail grocers first using the term.
 
Another term for a “sale celebration” is “sellabration.” Similar sales terms include “saleathon” and “sellathon.”
