Hello,
I am a little confused... it sounds like you are thinking that you "need" geocoins. If that is what you are thinking, you do not. I had been caching for over a year before I bought a geocoin. Geocoins are just a fun addition to the game, but you do not need them at all.
If you just "want" them, then I apologize for the above and will say that you can sometimes get a good deal on this forum from people selling some, or on the website of some of the manufacturers (sometimes they have "overruns" or such that they sell cheaper) - please be careful of buying on ebay as those might be stolen - also, make sure that the ones you buy are un-activated. There is a "geocoin" portion of this forum that might be more helpful in this issue.
Welcome to Geocaching!! and have fun!
Thank you for the response. I didnt know that a lot of people did it with out the coins. Thank you again for the helpful info.
