Have been waiting since Sunday for my pack to show up. I know that it doesn't take 5+ days for priority to get here when the shipment was marked as sent on Monday. I have ordered from this vendor before, but it does seem like his FE sale for free shipping does seem a bit suspect...
Take a look at recent threads. You're not the first person to complain about slow shipping times over the past 2-3 weeks. There is something going on that is causing delays. As best as we can tell, some packs have only just started moving again, which were shipped 11+ days ago. Tracking apparently indicates the packs were sitting in a sorting facility. There might be something going on near one of his closest post office hubs that's getting packs stuck for a week or more before moving on. However, 5+ days seems a bit short to be complaining, particularly if you haven't contacted him first.
