so when I was buying something from Nordstrom balenciaga yest I found out that they write down your entire credit card #, exp date and what you purchased on a note card and put it into this roledex type of thing to keep track of your purchases/returns. I am ok with the keep tracking thing, but to physically keep your entire CC # + exp. date makes me nervous. I asked the women why she was doing that and said " we sell so much balenciaga we have to keep track" which is BS..because they have had the same bags on there shelves since last year. what do you think about this?
