Instructions
Decide which stamps you are willing to give away from your collection. Many times, free stamps will involve a trade with another stamp collector. Determining what you are willing to trade will help expedite getting free stamps.
With your computer, log onto websites such as StampListing.com or StampTraders.org. Click the Stamp Exchange/Trade button. This will give you access to others who are looking to trade and exchange different stamps from their own collections, sometimes internationally.
Also with your computer, check websites such as StampListing.com and CraigsList.com for listings of free stamp giveaways and classified ads. You can also list your own stamps on these venues.
