Lots of consignment and resale shops find Facebook posts like these very useful:
Today Only: All pants 25% off!
Flash Sale: 50% off all lamps today
BOGO: Buy a sweater, get a 2nd half off! Today only, hurry in!
and that’s great. But before you turn out the lights to go home that day,
go back and delete that post.
You do not want to disappoint those who didn’t see your post until tomorrow. The polite folks will be disappointed and probably decide to wait until you reduce your prices again…
and the impatient, harassed, rude customers will storm in tomorrow, insisting that they get to have the deal, even though they know well and good that post was from yesterday or three days ago.
