Ya know, this is something that astounds me every time I read this kinda stuff. It goes with..... using a cheaper ink for your printer, cheaper media, cheaper supplies or hardware. Cutting corners to save what ?? PENNIES ??
If you build the going prices into your work, you're totally covered. If you keep your prices where they are and use lesser materials, you're cheating your customers. If you're using cheaper stuff to compete with the schmuck down the street, since when did slackers set your reputation in motion ?? Why make your MO the same as some hack ??
When you find something which works, why look further, just because it's a little expensive ?? Just pout it into your pricing.
