What is the difference between frugal and cheap?
A frugal person will try to buy quality stuff, but probably wait for a genuine sale and find a coupon or use cash back (or both) to offset some of the costs.
A cheap consumer just buys whatever they can find at the lowest price possible. In other words, frugal is good, while cheap (in relation to a person) is bad.
"Go to the ant... consider its ways and be wise!... It stores its provisions in summer and gathers its food at harvest" (Proverbs 6:6, 8).
