Dear valuable customer, as we are located in Singapore, the price offered here is based on ex-Singapore. We have to add in the freight and shipping insurance cost for delivery to your home country , but excluding your local tax , duties etc if applicable. However if you plan to self-collect in our store, this is most welcomed, we have to add in Singapore 7% GST (Goods and services tax) over the total purchase. This amount can be refunded at our Changi International airport, if you visit us as a tourist. Note that this GST refund is applicable only if you depart within 30 days from date of purchase. We strive to let you enjoy the purchase from us and have a wonderful experience with Expandore.
