Yup. Any site that claims they get LV "factory seconds" or that they get them "wholesale" is a total scam.
And yeah, there are several legit reseller sites. off the top of my head, these sites are: fashionphile, let-trade, karen kooper.
though before purchasing anything from any second-hand site you should post links to the item in the "Authenticate this LV" thread, and have the experts check it out, just to be 100% sure the item is authentic. Mistakes do happen and even very reputable hi-volume sellers have occasionally had a fake "slip-thru the cracks" and end up on their site. but this doesn't happen often, and when it does happen the tpf'ers are quick to set 'em straight!
