It seems like PayPal holds is something to be expected on Webstore.com as sited in this review - Link hidden: Login to view where buyers are encouraged to use PayPal for payments.
Sorry to hear of your present circumstances, hopefully this can help you cope with the payment hold - Link hidden: Login to view
Please note that the hold is initiated by PayPal and not Webstore.
Have you tried Addoway.com or Bonanza.com as an alternative to eBay? If you haven't, I recommend you check them out for yourself. For more alternatives, you might want to check out the list on this thread - Link hidden: Login to view
