This happened to me today. An item that was in stock yesterday(Bethlehem Lights wreath - multi-colored lights- As Is) went to backorder this morning. I ordered a different item similar to it (swag multi-colored lights - As Is). A few minutes ago, the backordered item was back "In Process".
I was afraid the backordered item wouldn't come in time for Christmas, so I ordered the swag. There are no more "as Is" wreaths or swags (multi-colored lights). I hope both of these orders go through - but they mght be backordered.
