If you didn't have time to get a card in the mail, you can still send dad your love and appreciation electronically.

Several sites offer free e-cards for Father's Day. Here are just a few of them:

Blue Mountain offers the option to not only send an e-card, but also to select a gift for dad from Mrs. Field's cookies.

Hallmark offers a variety of free and subscription e-cards.

1-2-3 Greetings has a selection of regular and animated Father's Day e-cards.

E-Greetings.com also offers free e-cards.

Yahoo greeting cards (hosted by American Greetings) has both free and subscription service cards for Father's Day.

Finally, for dads with a good sense of humor, try an e-card from someecards.com whose motto is "When you care enought to hit send." One of their Father's Day offerings: Happy Father's Day to a dad who was smart enough to teach me how to mow the lawn so he wouldn't have to.

Happy Father's Day!
