This contest fulfillment package was recently mailed by Young America on behalf of Hershey's. It was mailed in a nondescript, plain white envelope.
The recipient won a minor prize in a contest - a free Reese's product. This was communicated on a plain, white piece of paper. The package does not need to be fancy because, hey, it's a prize.
The coupon appears to be good for a candy bar.Fail for Timing because it was received on August 18. That gave the recipient only 2 weeks to claim the prize. That is not an adequate response window. If a prize winner is slow to read the mail, that person may be upset if he/she misses the window to use the coupon. The coupon could have easily been marked to expire 9/30/10 or, even better, 12/31/10.
Lesson: Even for a totally free item, there should be adequate time for the consumer to take action in response to your mail.
