In the frame of a single transaction, and the point I'm making, it doesn't matter which side of the purchase equation causes the deflationary more-for-your money effect.

The point is that the more-for-your-money effect does not stop even discretionary purchases like TV's from happening.

It slows some things like computer purchases. Puts a lag on a variety of things.

Also, why bother to invest money if you can just sit on the cash and benefit from everyone else's economic activity?

Deflation bad.
