Sampling is not just for new customers.
Companies use it effectively
to upsell current customers.
For example:
Schick included two “free” Xtreme3 razors
in a 10 pack of their value priced SlimTwin.
The Xtreme3 is one price point up
but it is enough of a difference in quality
that users will feel the difference.
Schick also packaged the two “free” razors
in the bottom of the bag.
That way, that quality will be the last experience
the purchaser will have before buying a new set.
How can you upsell your current customers?
