You only need to connect to the Internet when you logon (to make sure you've got the latest products, prices and promotions) and when you're ready to 'checkout' and send us your order - you don't need to be online when you fill your basket.  When you register and connect to the Internet for the first time, it will take longer than subsequent shops as all of the products, prices and promotions will need to be sent to you.  It will be a lot quicker the next time you shop as you won't need to receive all of the information again, just anything that has changed.
