I book everything online.  From travel to tables for dining.  Besides, ordering books, CDs and DVDs are usually cheaper and have no delivery charge on some websites.  The only thing I learnt not to order online is clothes, as not much care is taken with what they send to you.  I received the wrong item and the wrong size with one company and didn't bother since.  I must try grocery shopping online, but I don't like the idea of £5 delivery on top of my weekly shopping bill.
