Unless the client is actually displaying a countdown, it has no need for the data. All
the client needs in this case is a polling mechanism to occur on a set interval, whether
or not it intends to display any countdown down. No data needs to be pass back to the
server. All the client is essentially asking is "coupon?". Server either gives
a coupon or something else that is of no use for anyone to manipulate.

To elaborate on that idea:
Client asks the server and the server either sends the coupon or the
time left. The client then acts differently depending on the received
data. This way there is only one request made in either case.
