Scenario 1 - You have some family in another state that you never get to see. You want to send them a little note letting them know that you miss and love them. However, you don't have any postcards lying around. Order these. Problem solved.
Scenario 2 - Some ludicrous, turn-back-time laws are getting pushed through congress. What better way to voice your opinion and spread some love while you're at it... than to write your representatives on these awesome post cards. Do it.
5 postcards for a buck. 10 for 2 dollars. 15 for $3. Got it? Good.
