You're too kind. When you say "who should know better", you are assuming that he doesn't know better. NOT! This is purposeful misleading advertising with one objective -- to sell chips by whatever means necessary. Whether the buyer is mislead or not is immaterial. The fact is, the word "RARE" attracts eyeballs. The more eyeballs will in most cases lead to higher bids for the items in question. I believe the tactic works. You may laugh, sometimes I may laugh, but there are innocents out there that will buy chips assuming that what they are reading is honest and accurate.
