With very few exceptions, every successful piece of direct response sales writing I’ve ever seen is built around a special offer. The most powerful special offers urge you to take immediate action. 
This is done by setting a time limit on the offer. The strategy is simple: Limited-time offers motivate prospects to act sooner, rather than later.
Example:
Order by September 31, 2015, and receive a 25% discount off our standard everyday price.
If within 30 days you’re not completely satisfied, we’ll give you a full 100% no-questions-asked refund.
There you go. A limited-time special offer combined with a money-back guarantee. However, you can always add greater value to your offer by including bonus items.
And a P.S. line is an ideal way to promote them.
Example:
Order by September 31, 2015, and receive a 25% discount off our standard everyday price.
If within 30 days you’re not completely satisfied, we’ll give you a full 100% no-questions-asked refund.
P.S. Plus, we’ll also send you our FREE e-book, 7 Steps to Doubling or Tripling Your Leads in Under 30 Days! (A $39 Value!)
Even if you return our product within 30 days, our FREE e-book is yours to keep!
If you take a look at my examples, the second one clearly stands out as the stronger of the two.
All your direct response sales letters and website landing pages should include a P.S. line. Even if you don’t have a special bonus to give away, a P.S. line is a great way to reiterate your unique selling proposition, or the main focus point of your landing page.
It’s a fact. Research shows that people’s eyes gravitate to P.S. lines. So use them!
Plus, common sense tells you P.S. lines are a great way to enhance your persuasive sales copy.
Why? Because everyone knows there’s always something juicy or important in the P.S. line. So take advantage of this!
My theory is that it goes back to the letters and notes we passed back and forth when we were kids. Remember writing stuff like this…
P.S. Don’t tell Jimmy that Shelly has a big crush on him!
People know there’s always something juicy in the P.S. line. That’s why nearly everybody reads them.
So put this to work for you and make sure to include P.S. lines in all of your persuasive marketing pieces.
