Go to Hershey's.com and click on Enter UPCS. If you do not have any UPCs they will give you 2. Then you can choose between a code for a desk calendar or a mug. You will then get an email like the one below which will have your redemption code in it.
Sample of my email (without the code of course lol):
Thanks for participating in HERSHEY’S ‘Make Moments Last’ promotion; you’re just a few steps away from completing your order for a customized mug.
First, you’ll need your unique ‘Make Moments Last’ code. You’ll need this redemption code to complete your order, so keep it handy.
Second, click on the following link to Snapfish (or copy and paste it into a new browser window). http://promo.snapfish.com/hersheys_mug/customerappreciation
Third, follow the instructions on the Snapfish website to complete your order. Remember, there is a $4.99 shipping and handling fee to complete your order, so have a credit card handy.
**Your credit must be used before 4th February 2011
This would make a great Christmas present for someone!!
