This is JMHO but
debbieb208 and
gutless girl's response to having been called out is further reason for me to avoid her and certainly not recommend her as a seller either on ebay or on Etsy. (I haven't checked Bonz yet so I don't know whether she sells there.

)
Although it's a seller's responsibility to know items are authentic before listing them, we're all human and capable of errors. It's one thing for an honest seller to mistakenly and unknowingly list a fake. It's quite another for a seller to lie and claim that she had items authenticated by Coach when it didn't happen.
There have been other sellers who have joined TPF after having been caught (unknowingly) with a fake. Perhaps
debbieb208 needs to join too.
