I currently use my macbook pro in clamshell mode a lot with the apple wireless keyboard and apple magic trackpad and I also purchased the apple battery charger with 6 rechargeable batteries. What do you think I could sell my current keyboard/trackpad/battery charger & batteries for on craigslist?
Tell me if I'm wrong but I think your'e referring to the first gen Apple Wireless Accessories for Mac.
If they are in GREAT condition, sell em for about 70% of the original price.
If they're in ok condition, sell them for about 40% of the original price.
If they're heavily used and not in great condition, sell them for 15% of the original price.
You did state that you are selling them on craigslist, so remember not to throw a low-blow. Always start on the high end when selling, and negotiate for a lower sell price from there. For a quick painless transaction, go with what i stated above.
