I feel for this generation. The 20s can be an exhilarating time of life, a time when you're making some of the biggest decisions of your life: where to work, whom to marry, whether to have kids, where to live. It can also be confusing and scary. This generation, however, has the added prospect of economic uncertainty rarely seen before. Their great-grandparents lived through the Depression and came out better for it, some say. But the difference today is that kids in the Depression moved from hardship to affluence as the postwar economy kicked into high gear. Today's generation is doing the opposite: they're moving from a childhood of affluence (even if only on paper) to a bleak economic future. That has to alter the equation.
Try for store credit
Sometimes a store credit or exchange will be allowed, even if a return will not. Take advantage of store credit to get something you actually want! Try to return as soon as possible, though. If you don't have a receipt , you'll end up getting back what the lowest price of the item was, and not actually what was spent!
