This is one source of inspiration written over 100 years ago:

========================================================
PRICES

It’s unwise to pay too much. But it’s worse to pay too little.

When you pay too much, you lose a little money, that is all.

When you pay too little, you sometimes lose everything, because the thing you bought was incapable of doing the thing it was bought to do.

The common laws of business balance prohibits paying a little and getting a lot. It can’t be done.

If you deal with the lowest bidder, it is well to add something for the risk you run.

And if you do that, you will have enough to pay for something better.

There is hardly anything in the world that someone can’t make a little worse and sell a little cheaper – and people who consider price alone is this man’s lawful prey.

John Ruskin
1819 – 1900

And the more sophisticated the product the moreso, and is very applicable to the IT industry and VARs, in particular.

I hope I am not giving my competition the secret by posting it on this blog….
