No. If a person was selling a coin, I'd have absolutely no problem with someone wishing that he "makes a bunch". I would wish that he makes a bunch. The buyer base for coins is well more than 1000 (maybe 10,000 or 100,000) times that of chips.

The chip community is, relatively speaking, small. Many ebay transactions are from sellers I know to buyers I know. Somehow, I hope you understand, I feel more protective of the chip buyer.
