Where to find a lense cap that fits my camera?

I just bought a digital camera from CL and it didn't come with its original lens cap. I have an Nikon L105, can i just go to a camera store and find one that fits?

As long as you know the filter thread, yes.

If you don't know the diameter, just take your camera with you and see if they'll let you try a couple.

Since the front of the L105 isn't fully threaded like a DSLR lens, you might only have the OEM choice. The cap you need is the Nikon LC-CP20, available at Amazon, B&H, Ritzcameras, and directly from Nikon. You'll find it going for $9.95.
