Does heat stamping take away value?

Is it really free? Sorry, I'm one of those people who always thinks "If it's to good..." call me a pessimist! :shrugs: Do you have to bring proof of purchase to the store?

No need to show proof of purchase. :yes: I took a few used LV items (purchased from ebay) to the store and they heat stamped w/o questioning the origin of the bag.
