You can do a search on ebay for them, type in disney lanyard... it should bring up a couple thousand. LOL. We purchased ours from ebay, I have the one that is a zippered pouch (I hold all of our tickets - my children are young, and my husband is... well... lets just say I hold his too

) Here is a link to the one that we have purchased:

I like it because I feel like the zipper is much more secure than just the plastic sleeve that most people use. Also, there is a clear plastic sleeve on the back side of the pouch that I put my "touring plans" with all of my necessary info (ADRs, etc...)
HTH
