A very powerful motivator for all of us is
the fear of loss. We are much more strongly motivated by this than we are by
the prospect of gain. So, when you create a special offer for your customers
(motivation: gain) include a time by which they must order or else they will
miss out (motivation: avoid loss). This way you give them 2 reasons to buy from
you, rather than one.
You’ll see companies selling seminars doing
this a lot. It allows them to judge the demand, and therefore decide early
whether to cancel, step up their marketing, or reduce their marketing because
they are approaching capacity.
You can make this offer even more powerful by being
a little vague about the closing date, e.g. “for the next few days only”.
