The original post does not say whether the prior chips actually sold. I am assuming from the discussion that they did sell. In any event, I have personally found that a marketplace is a place where you can become informed, but seldom by the seller!

I have also dealt with many buyers who lack even the slightest idea what they are bidding on, which makes me feel slightly guilty that I might just be feeding addictive spending habits. I sell Matchbox and Hot Wheels cars, and you would be amazed at how many buyers have left feedback complaining that they thought they were buying larger scale models - even though I advertised them as Hot Wheels and Matchbox cars. Mind you, these sell for $2 each and ship for around $2 as well! After the third complaint I started including a warning that these toys are about 3 inches long. Now, can you imagine having to put a warning on every chip listing that chips are a certain size, and the chip they receive in the mail may not be as large as the photo on their computer screen?

When it comes to ethics, there are some basic rules in buyer/seller situations: advertising must be honest. It does not have to be complete. Buyers who find a bargain do not have to pay more than the advertised price. And no one looks you in the eye on an internet auction site. I think it's great when people hold themselves to a higher standard, but a certain amount of caution is still warranted.
