Are these calls from south florida or new jersey?
I get them almost every day from two places, one is a "car warranty" jobber, the other is a "lower your credit card interest rates". I cannot get them to stop calling.
Bogie checkout vistaprint.com. They have some mass mailing options. They have some free stuff you can take advantage of, too, but be careful at checkout and read every check box so you don't end up paying for stuff you don't want.
