Am sure you, as an experienced eBayer, are aware that there was an estimated delivery date in the listings when you made your purchases. Those dates must have been acceptable to you or you would not have made the purchases, right?
First of all, all items do not always get tracked on their travels. Second, it does not really matter when a seller ships, as long as the items arrive before, on or even slightly after the last estimated delivery date. Even if the sellers reply to your inquiries, or even says, "have not yet shipped", there isn't anything useful you can do until they are actually late. And I know you are aware of that.
My advice, which possibly you won't care for, is to just wait for the arrival of your purchases, knowing that you have eBay's MBG for buyers if anything goes wrong.
