Yes, you are correct. I used to buy them on eBay and then sell them back on eBay and do nothing but divide the kits up into single camera/lens. I made money doing this. 07-08.There are still some folks out there that prefer shooting with film. I think it is largely because it is more of a challenge in photographing and developing. At one time, I had an Asahi Pentax Spotmatic, a Minolta XG-1, and a Canon T50. Both the Pentax and Minolta had extra lenses. I was finally able to sell all of the stuff at a garage sale to a guy whose granddaughter was going to take photography classes. I didn't get much for them, but I know that some young lady may be enjoying the heck out of them.
As stated by others, I would also check with E-bay. Also, there are some websites that buy used camera equipment. You might check out KEH Camera as they sell and buy.
