Amazon delivery. Damned impressive! Receiving some packages overnite for free. Others within days, for free too. Realtime tracking of the amazon-contracted courier on googlemaps..
I discontinued prime because their 2 day shipping was 5+ anyway thanks to my local usps. Not amazon's fault, but they partnered with some shady, fly-by-night government agencies.
I too am a Prime member. Ordered $150 worth of Blu-ray Sunday afternoon. Selected 2-day shipping. Arrived today... 6 days later. We jumped on Prime when it was first rolled out. Was damned impressive then. About two years later, the shipping end of it went to shit.
