This happened before too. Either I lose my mind or I lose deals.
For example I saw an ebay deal yesterday giving 10% off from certain categories but I can't find it today. Assuming it's been removed, when a deal removed can't we get a small information banner where the deal used to be telling us what happened/why it's removed similar to duplicate deals?

They were duplicates. They were removed so if you accessed them they would automatically forward you to the original.
