The Cash Shop window.
Cash Shop or Boutique is the shop from which players can buy a variety of items using Gold. Gold can be bought with real money or through the Auction House with game coins via Gold Trading. Some items are permanent while others are only available during special sales. The Cash Shop is updated every week with various items going on or off sale.
The Cash Shop can be accessing by pressing "O" or by clicking the yellow icon under the mini-map.
Buying Cash Items
The interface is pretty simple to use. The tabs along the top take you to various different types of items that you might want to buy; click the items to get a better explanation in the panel on the left.
The 'buy' button is grayed out if you don't have enough Gold (listed on the bottom left). When you do buy, it asks you to confirm, and if you confirm, the item appears in your Inventory immediately.
What Can I Buy?
If there's a special sale on, the sale items will be on the first page. However, some sales do not appear on the first page, and can only be found on their usual page. A prominent example of this is Fashion sales that open their own window within the Cash Shop.
It is worth noting that there is always something on special offer, exactly what it is usually changes each week, and sometimes things are available for a single weekend or a single day. If you want a particular item, then you may do best to wait for it to come around.
