How to place an order?
Select a category in the shop and browse through the articles. If you have found what you are looking for and would like to purchase an item, click on Details first. In the following dialog you may get more information about the article and an input field where you can enter the desired number of pieces (possibly limited to min / max.).
Then click on the "Add to Cart" button. If the article is available in sufficient quantity, it will appear immediately in the shopping cart.
Go to the checkout and follow the prompts as you proceed.
Only when all the required information has been completed does the button "Order" appear.
