If you receive dated gift certificates or other premium rebates to use in a particular store, note the date on your calendar and which store it is to be redeemed in at least 7 days before the expiration. That way, you will have a reminder while you still have time to do something with it.
Editor's Note: It is also important to know that some gift cards expire. If you have a gift card that you have gotten for Christmas and have been saving, you should research when that store's gift cards expire so you can be sure to use it in time. Not all stores have the same policy in regards to gift cards so it's important to research if you aren't planning on using a gift card within 6 months of receiving it.
