We all know if you want a Birkin or one of the Balenciaga blazers, you'll have to sign a waiting list. But we recently discovered that even some un-coveted items also have major restrictions. Yesterday, a lot of you concurred that buying an expensive piece of luggage, like this Prada duffel bag, is stupid (and kind of silly.) And yet, you can see on Saks that its purchase is restricted to “no more than three units per customer every 30 days” due to popular demand. A quick search to see what other items are restricted reveals dozens of pages filled with similarly disgusting merchandise. So who’s buying all this stuff, and in droves? We know there are more logo-driven shopping cultures out there, but we somehow doubt that they're trolling Saks.com for slightly cheaper Gucci Moccasins. And if you're thinking people overseas buy Gucci, then turn around and sell it on Ebay, we're not sure this theory holds water. We checked a few items on international eBay sites, and they either weren't sold from another country, or they were going for much, much cheaper than retail. Why the Prada embargo?
