At the small quantities involved in retail sales this is how it works." Well, in this particular case, the keyrings was sold from a large case on a pallet next to the cash-point, and the keyring was also advertised in there direct mail adds. I'd expect there keyring/batteries ratio to be (during this weeks) something like 1000-to-1. And, anyway, most buy it as a "miniature lamp", not as a "keyring"...
