An amount of money that is well beyond
pocket change or what you'd normally spend on any one thing but isn't in the same league
expense wise as a new car or house.
An example could be a new computer that you might need to save up for a while to afford.
Another example might be eating at a
really expensive restaurant. It's not costing you the same amount as a new computer, but it's still far more expensive then a typical meal.
Look, I think we're going to have to choose somewhere less expensive to eat. I love the food there but it costs a
small fortune.
Yes, I know I need a new video card but I can't afford
the small fortune that a lot of the ones you're recommending cost.
