My stupid Louis Vuitton purchase...

Sorry to hear about that. I agree with the posters who suggested ebay, and not going into debt for a handbag.
It's good that you learned this lesson while you are still young! Cut your losses and learn from your mistake.

Also, it is only money and it will come and go.. sounds like you still live at home so you'll be able to save up more in a matter of no time. Also, repay your family for the money they've loaned you.
 
This is certainly frustrating to read- I remember you refused to take the advice of EVERYONE on the money subforum who told you to return the item (and yes, this was within your 30 day return period).
