eCards
Though convenient the e-card has not been able to replace the traditional greetings card completely. When you get an e-card you stare at it for a minute of two and forget about it but with a traditional card it is not so. When you receive a card by post, the entire family enjoys receiving the personalised card.
Also as the card is around the house for some time at least you will have the card in your memory for some time. The only advantage with ecard is its speed. Some internet based companies realizing the value of the traditional card undertake to make personalised greeting cards. They also undertake to mail the customized cards to the intended recipients.
