It isn’t just the dollars and cents on the price tag. Yes, that’s the upfront cost, but if you base your purchases on that alone, you may be in for a sour deal.
Have you considered:
The cost on the environment
The cost on your health, or potential health risk
The cost of your effort every time you need to move it
The cost of it forcing you to exert mental energy
The cost of future time that you will spend using it
The ongoing cost of it taking up space in your house
The ongoing cost of maintenance
The ongoing cost of cleaning
The ongoing cost of keeping it organized
The ongoing cost of it distracting you
The ongoing cost of it worrying you
The tolls of all these costs on your friends, family, and neighbors
When I think of the total cost, it's hard for me to find much that is worth buying.
