You'll get alot of junk mail, but then again all you have to do is ignore the address and put e-mails from those sites directly into the trash. I don't usually put my phone number out, unless I'm ordering something from them. They won't use your number, unless a problem in shipping arises, which occurs occasionally. Free stuff doesn't always come, so get your hopes up too much. I doubt this Tellme shirt will....speaking of which DOUBLE POST....and you are a SENIOR member bigbigsavings...What gives? Anyway, overall nothing is going to happen other than some junk mail sent to the house or e-mail account or accounts. Your name, address and everything else about you is already out on the net, through phone books, so don't worry about it.
