I have a "junk" email address. The only time I even look at the thing is when I have to verify a new account. For all I care, a company can send 5,000 emails a day. I never see them and nothing of import ever goes there. As to phone number, I just give them this area code with my old phone number. Birth date: my daughter's day and month, my year minus three. This way, I can remember all the relevant data if I need it but still keep some privacy.

I did use my phone number when I had a Winn Dixie card. But, I am concerned that the Plenti card is not controlled by Winn Dixie, but by a much larger organization that could distribute my phone number to a much larger group. However, that is just my speculation, but I am concerned about it.
