Granted I've never been in to a FP boutique, only the Outlet stores, but have only purchased FP items on super awesome sale...I've never seen them black out a tag. Anybody else seen this at FP boutiques?
Just an idea, the blacking out could be like what other outlets do to labels to prevent returns to the full-price stores. I could be wrong, but I would think it has nothing to do with the country of origin.
