I used to just "throw in" cheap stuff to buy and sell listings. I don't do that anymore. Step-up rings, lens caps, back caps, adapters, lens leashes, hand grips, gariz buttons, remote releases, filters, etc. When I listed things I wanted to move, I'd add some of those to sweeten the deal. What they heck! You can buy another one. I stopped doing that when I realized very few buyers actually value them. Now I have a drawer full of little parts, and I can't count the number of times I've ended up using something! Especially lens caps. For instance, I recently purchased a CV40. I think it has a 43mm thread. I happened to have kept my 58mm filter from an old canon, and had a step-up ring for 46-58mm. I got a 43-46mm step up, and can now use my 46mm screw-in hood from my Panasonic 20/1.7 (since sold) and my after-market 46mm pinch cap, with the 43-46 step-up ring, and then add the 46-58 to attach my new 58mm Moose filter (warming + CPL), so I can use that one fillter across a couple of lenses. Money saved! I'll still toss in batteries, because unused batteries become dead batteries, and slow SD cards that I can't sell, but the rest of the stuff, I'm keeping! Anyone else have some tips you've learned in selling gear? Not just "don't sell to the guy with no feedback" but maybe something more unusual?
