I changed the prices
of two of my books
at Kobo.
Within an hour,
Amazon had
price matched it.
The world is connected now
and there is no one
a business entity
follows closer
than competitors.
That means
there is no longer
any
quietly testing of a price
or a package configuration
or some other feature.
Your other customers
will know about it.
Assume when you offer
a special deal or pricing
to one customer,
ALL of your other customers
will find out
and want the same deal.
What you offer to one customer,
you offer to everyone.
