If you are feeling rather cheap and do not want to spend money on your significant other, Valentine ecards maybe the way to go. Sites on the internet offer them for free, and you can even customize them to suit the likes of your partner.
A word of warning when receiving a Valentine ecard, as some people try to exploit innocent people who are just happy to have received an online card. Do not open any card sent to you by somebody you do not know, as it may actually be a virus waiting to infect your personal computer. Will you be sending any ecards this year?
