What is the connotation for the word "cheap", versus "inexpensive"?

Bad quality

Explanation:

Both words "cheap" and "inexpensive" have the denotation meaning that something is "not at all expensive, or lower in price than you expected". "Inexpensive" is cheap and of good quality for the price you pay. On the other hand, the connotation for "cheap" often suggests it is also bad in quality ("Buying cheap shoes is not a good idea in the long run. "); it is something low in price and quality.
