“Cheap” implies less of everything that is important, not built to last, minimal attention to the detail, and certainly little customer service. However, “Frugal” implies a discipline that ensures that waste is eliminated, unnecessary features eliminated, but the basic performance is not compromised.
Cheap is never the outcome of good marketing, but Frugal is a very potent positioning in most markets, and is often ignored in the search for wider customer appeal.
Next time, ask yourself, if it is cheap, in which case, don’t buy or produce it, or frugal, in which case it may be a good deal.
