I went to their website tonight, about 4 hours after the posting about the sets being available. None were available for shipping, but the site showed that the Mandalorian Fighters 75022 were in stock, available for store pickup. I ordered 2, and got an email a couple of hours later, stating the items were ready for pickup. But, reading the email closely showed the items they are holding for me are 2 Desert Skiffs. Only similarity with the Mandalorian Fighters is that they are Star Wars sets with the same price point.
I might mention that my last purchase from KMart online was for several Lego Friends Stephanie's Pet Patrol. They shipped me the wrong item, which was Friends Stephanie's Soccer Practice. Evidently they didn't have any Pet Patrols and didn't know the difference between the 2 sets. Just like they now don't know the difference between a Mandalorian Fighter and a Desert Skiff. They don't seem to know about UPC codes. Bumbling and clueless are the nicest words I can think of to describe them.
