Mike,
I don't think that is all that unusual. Your items that are backordered are only a week away. Had it happen many times, from a variety of companies. If they were several weeks or months away from shipping, they probably wouldn't charge you yet. I know how anxious we can get waiting on an order of "goodies" to get here, just sit tight, they'll be here before you know it!
Good luck,
Trebark
