Here's a fun offer. Text the word PEN to the number 62999 to get a free Paper Mate gel pen from OfficeMax.
This offer requires three texts in all: the initial text, a second one to submit your name and a third to submit your address.
It took me all of about 45 seconds to complete. The pen is supposed to arrive in seven to 15 days. Cool.
Obviously, this is only a good deal for folks with unlimited texting plans.
