The Boston Globe recently wrote an article entertaining the ethics of "borrowing" an item and use it accordingly then for the particular purpose and then return it within its return policy.
Confused yet? It's quite common actually. More in women when it comes to clothes or shoes for a big event such as Prom or a Wedding. They love a dress or a pair of high heels but feel like they do not want to spend all that money in order to purchase it. So . . . they buy it and return it the next day. It is something that is practiced by celebrities all the time except Armani or Gucci wants them to wear that dress (so it is a little different).
Men had recently picked up on the practice and apply it to electronic goods. For example someone might be need a TV for the night for a party or small DVD player for a long road trip over the weekend.
Is there something morally wrong with this practice though? Retailers have caught on and entering into evasive policy returns that make it hard to return the item even for a real consumer. For more on this, check out the article here and entertain the issue . . . at the end of the day we are all consumers.
