That's pretty much the same scenario here. They had one shipment of one case of wave 1 comics and then one case of wave 3 comics about a month ago.
They have two pegs marked for singles but they have just been sitting there empty, with an "ordered" sticker dated March 6th, 2008. An associate told me they were "in-transit" when she scanned the tag but that was at least a month ago.
