^ ^ ^ Absolutely.
I agree with previous posts, it's absurd for PS to suggest that they can't authenticate their own bags.
If it is truly their policy that they will only provide warranty benefits when their authentic product is purchased from authorized retailers, then I sadly will have to limit my purchases to seasonal sales. There's no way I'm giving PS nearly $2K per bag just for the privilege of quality control.
(But I must say it's a small step up from Balenciaga, who refused to fix a bag I purchased directly from Bal.com, when the strap broke less than a month after I bought it).
I've had reasonably good luck with designer accessories over the years, but after my experience with Bal and now this news from PS - I'm going to adjust my shopping philosophy to "Only buy what I can afford to break."
