The other day I went to send a card to my 2nd cousin on my mothers side. We have not stayed in touch all that much, but we are still close enough that I needed to send a card. He had contacted me a few times in the past year, so I had his phone number. But I have never had his address. However, I feel that we are well past the point to ask for his address. So I used reverse lookup to find his address to send the card. It was so easy to use, and I plan on using it again.
