How quick they are to deliver and ship! No other retailer can beat them! The only disadvantage is most things are shipped USPS and they deliver late in the day here I prefer UPS. Lucky the next thing I ordered is coming UPS this time! I got lucky! Of course this is with only items sold by Amazon or shipped by Amazon if there is a different seller. Otherwise the quick shipping and delivery does not apply. Though most things are sold or shipped by Amazon nowadays. My example is I ordered something yesterday and it will be here tomorrow! That is very quick if you ask me!
