when you request a Service in USS, you add it to the cart as in other webshops like amazon. But after you have added it, the page refreshes and you are back on the "request a service" page of USS. Here you don't see the link to the shopping cart. You first have to go to "My requests" and there you see the link.
This is not intuitive at all. It would be very helpfull to have a link to the cart also on the "My request" page
