Handy Key Light

The tiny light snaps onto the base of your key and has its own loop to attach to your key ring.

You push the button to illuminate the keyhole.

A replaceable bulb plus battery are included in the 1.38"–square black plastic case.

But why would you bother replacing the bulb when you could simply buy another key light for probably less than the cost of the bulb, not to mention the fact you'll never be able to find a replacement bulb?

The key light costs $1.99 here.

Here's what's odd: if you buy two or more the price drops to 99¢ apiece.

So my question is: why would they bother offering to sell you one for $1.99 as opposed to simply pricing them at 99¢ each?

Who would buy just one when it actually costs more — OK, only a penny, but still — than two?

Truly a mystery of American commerce.
