My SA used the term "rack" when discussing my order after I placed it. She never mentioned that it was a special order, but it ended up being a bag with a contrast lining, which I assumed made it a special order. Later, she explained that it is a "rack" order, which means that the SM submits a list of bags ordered by clients in specific leathers and color combos, but Paris only allots each store a certain number of orders per year, so whichever bags were not made that year get resubmitted the next year. It sounded exactly like a special order to me, and I assumed it was just different terminology for the same thing. I guess what Birkel describes could be true, that it is a podium order for a specific combo that a customer requests...but mine certainly has not arrived in the time frame that a podium order normally should, and my SA specifically said that the leather and style of bag that I chose had to be ordered, that they would not come as part of the normal store order for that season. It's all clear as mud to me, and at this point, I don't care, I just want the darned bag to arrive sometime before I'm too old to carry it.
