Input: Text: i work for a major cell phone company and i have a side hustle of buying cell phones and reselling them. 

one of my best friends mom had an iphone 6 plus that she was getting rid of since she switched to another carrier and the first person she thought of to sell it too was me. 

the tfiu part comes in, where we live 3 states away. myself in louisiana and they live in florida. she needed the money asap and didn't have a bank account. my illogical but spontaneous idea was to just fold cash up in paper and send it through the mail. it's been 8 days and they haven't received the envelope. safe to say it's gone. lesson learned. don't send cash in the mail.
