Anything that's inexpensive doesn't cost a lot. The inexpensive camping trip your family takes, instead of flying first class to Disney World, might turn out to be a lot of fun!
Inexpensive things are affordable, sometimes because they're cheaply made, but often because they're reasonably priced. Check out the thrift stores before you buy those $200 jeans — you might find an inexpensive used pair that looks identical! Or cook an inexpensive meal at home instead of eating at a fancy restaurant, and you'll have money to splurge on dessert. The Latin root of expensive means "weigh out money," and the prefix in- means "not."
