Where can you buy 400 microsoft points?

Microsoft Points are sold in each sovereignty in the local currency. However, because the official price per point is defined differently for each country (in terms of their local currency), some regions pay more for the same quantity of points than others due to currency fluctuations. Microsoft Points are purchased online with a credit card or with Microsoft Points Cards ("tokens") from retail locations. Points can be bought in a number of different allotments ranging from 100 up to 6000 Microsoft Points. In the United States, 80 points are equal to US$1.[2] As a result, an 800 point arcade game would retail for US$10 in real-world currency. The price of Microsoft Points varies considerably between regions. When launched, Microsoft Points were priced approximately the same in each country. However, because Microsoft does not generally change the pricing to coincide with the current exchange rates, the cost per point in other countries relative to the United States is constantly fluctuating. Depending on the registered country or address of an account, the online purchase of Microsoft Points may be taxed. The following list includes regions which must pay value added tax or luxury tax in accordance with government regulations:
