Yes, eBay has two International shipping consolidation points, Glendale being one of them. The postage charge that you pay is from your location to the shipping point. You can be guaranteed that your customer is paying more for shipping.
One great advantage of the eBay International shipping is that if your package is lost, you still get paid, and the customer gets refunded. I had such a situation just recently, AND the "Item Not Received" action will not count against your good standing.
