I would say either don't use it and give it to your mom for her birthday, or buy her another one. I know my mom would be happy to get a used bag that she really wanted and your mom might as well, I just think Moms deserve better! And don't get me wrong...I'm not made of money by any means (FYI both me and my husband are in law school). I wanted to get my parents an IMac for xmas, and one of my friends suggested I buy a new one for myself and give my older one (still great condition) to them. I guess I just find this a bit
tacky...If I'm gonna give it I want to do it right! This would be even worse if you gave it to her and then went out and got yourself something else to make up for the loss. I know I would be tempted if in that position
Just my honest opinion, don't take it personally or anything as I am sure whatever you decide your mom will love it!
