Wondering the same thing - they've sent me the same junk mail a few times, offering me $25 in free postage, yadda yadda yadda - it's tempting, but I've almost eliminated any need for stamps in my life... ?
Should I just get my $25 and my free scale and call it a day or is there a catch?
Edit: Well the fine print is certainly interesting. Even though the printed crap they send in the mail pretty clearly indicates that I'll be getting "an $80 value" the fine print says that what I get BEFORE my trial is up is a $5 credit, and what I get AFTER the trial expires is the other "$75 value" ... no thanks.
