i buy stuff from large consignment companes with these tags and although it might help from getting a fake back (i assume?), it doesn't help with someone actually using the item and enjoying it until they decide to return it. even if it's attached to the chain - which most on chanel bags are - it's so easy for someone to tuck in the chain and still use the bag. i know we all do things to help ourselves not get scammed, like videos and tags and etc. but nothing can solve all the problems when buyers are looking to scam.
This is true. Actual businesses can absorb these occasional losses through volume and through tax write offs. Not so for most of us though!
