internally consistent with
the interface for friends.

are also used here.

a good metaphor to
represent Rei has
something for you.
Cons:

also be problematic if
user falsely interprets
it as a chatting screen
like what's app. | Pros:

deal, viewing can be
done efficiently.
Cons:
1. If the list of deals is
long, users need to
scroll down on the list
to view the desired deal.
We should provide a
search bar with auto-
complete to help user
search for the target
offer. | One of the errors might occur
in this interface is not viewing
the desired data by
clicking on another deal's
picture. User can undo this
by going to the home
screen or the back button
on the browser.

clicking on "Terminate" too
quickly. A confirmation alert
could be used to prevent this
problem. | The coupon information and
the information user has
shared with the company
can be noticed easily.
However, we should test
whether users are able to
notice the difference between
the button "Rei' deal" and
the button "My LocaShare".
