^^^ This.
It did bother me when I saw LouKPeach's email to her supplier, she was obviously looking for quality fake Chanel to incorporate into her scam...
BUT scammers like her would NOT target Chanel boutiques since they do not give cash refunds, exchange only, and cash is what her ilks are after. So you are safe as long as if you stick to stand-alone boutiques
Honestly though, I'm sure high end department stores e.g. NM, Saks, Bloomie's, etc. will be cracking down in terms of return policy after this anyway, especially with brands like Chanel... but I can also see rise in copycat crimes. There were SO many comments on news media articles calling her smart, giving her credit, how they should try it, people who spend 2k on handbag deserve to be ripped off...
