I have bought my wife a Blue Label Burberry bag while shopping in Osaka. The best place to buy the Blue Label Burberry Bag is in Shinsaibashi, Daimaru in Osaka. You must be asking why I said that. I can get 5% Tax Rebate plus 5% cash discount on the Blue Label Blueberry Bag. Furthermore, this is not available in Singapore and you will pay more if you u get it from resellers.
You must pay by cash or use credit card with Union Pay which is meant for China Customers. Singapore certain credit cards also using Union Pay. Daimaru Blueberry staff can converse in English and the Tax Rebate Counter will have one staff which can converse in Chinese for China Customers or customer like me who know how to speak chinese.
