The flagship on 5th ave sells out of some of the more popular bags as a lot of tourists stop there. I love the LV in the Saks (also on 5th ave but on 51st street). Last weekend, the 5th ave boutique was sold out of several models of speedys and NFs, but they're probably restocked by now and have plenty during the week. They tend to sell out of the most popular items (NFs and Speedys) by Sunday afternoon in my experience but the Saks and Bloomies boutiques don't get as much foot traffic and don't have the same inventory issues.
