I've actually run into this with several other Steel book editions that they do. I think your best bet for getting delivery on 4K Steel books is to pre-order them many weeks in advance. If you don't and you wait until like the week of to pre-order or purchase you will only find them as store pickup. Again this is what I've found when ordering the 4K STeelbooks in the past, not sure why this is the case. So just make sure to keep an eye on release dates and pre-order well in advance to secure delivery.

As far as cleaning these goes a can of compressed air will do the trick, all you really need to do is keep dust from building up on them (which tends to happen with continual use). I would use compressed air on it every month or so if you use it constantly. These fans are well worth the $80+ you spend on them, we live in a 720 sq ft apartment and this thing circulates air throughout the entire unit. We put our's in front of our window A/C unit because we don't have central air and this thing makes it feel like we do have central air, never hot during the summer months. I highly recommend this product, you won't regret your purchase.
