Troubles to fill an order?

There are maybe several reasons.

1. Getting a message - "your shopping cart is empty"? Before to push a button " Click to pay" you have to choose the desired service and to type in an amount of the letters you want to send, or amount of addresses you want to order.

An example ( the red arrow shows the space to type in a simple digit "5" to order 5 addresses. Then push a button "Click to pay thru 2CheckOut")
