I don't usually like to sell on forums because 1 - things are slower to sell and 2 - it's usually more hassle than it's worth. I don't mean to offend anyone, but if you've sold much on the internet I'm sure you know what I'm talking about.
I like ebay auctions where the product usually will sell quickly and i nearly always do .01 no reserve auctions. In the case of these key caps, I got burned buying the Cherry keyboards. They were used in mechanic shops with key covers/skins on them so the keys were good, but the edges and backs of the boards were very dirty and the cords were as well. More dirty than I have time to spend cleaning. A couple are ok but rather than pay to ship them back or spend the time cleaning them up, I opted to just pull the 2 shots and sell them separately at zero profit. By the time I cover paypal and ebay fees I don't make a dime on these.
J888WWW, Andrew is right, It's just a keyword, caps themselves are not clicky but these caps are frequently used for clicky keyboards, thus the use of the keyword to help the right people find the auction.
I would be glad to sell outside of ebay, I frequently do, but for some reason forums are not as efficient at moving things when you want to.
I had 8 total cherry boards, I'm keeping 2 key cap sets and have already sold 1 set on ebay... so I have 5 more sets if anyone is interested you can PM me.
