annoyed in Wonderland: are you serious?

K-Mart sells cordless phones.

K-Mart sells batteries for cordless phones.

The cordless phone batteries K-Mart cells don't match the cordless phones they sell.

So if you buy a cordless from them you'll need to find somewhere else to get batteries if yours ever dies. Are these things supposed to be disposable? I know they're getting cheaper and cheaper every year, but what a waste of resources.
