というわけで今日は¥20,000はnot including taxなので you have to pay tax if you want to buy itなんだけど、you can get the tax refund after payingですよ、ただyou can not get full price of taxで、because our shop get 1.1% service chargeだから、なのでanywhere in japanならjapanese always have to pay 8% taxで¥21,600でno refundだけどforeigner can get tax refundなんだよ、so price will be this、という説明をしました
いつもこんな感じのカスカスの英語力です
恥はかきすて、ご参考まで
