There are two sample stores set up in this demo, one seller from the UK, which will apply tax on his items for buyers from the EU, and the other from the US, which wont apply any taxes.
Shipping is calculated based on the integrated shipping carriers is available in both stores, so you can get real shipping quotes on your test shopping carts. The sample store based in the US will ship in selected countries only, while the sample store based in the UK will ship worldwide.
In this demo, new users aren't allowed to list any items for sale.
