Prime subscriber here, though it's the UK model (next-day delivery on many things, plus Amazon Video as a perk). My approach on it is somewhat different to many others here. I can order some stuff before 8pm and have it delivered next day. Things ordered earlier in the day (pre-noon) could be any courier, but the post-6pm orders are almost always delivered by DPD to my area (north Cornwall, EX23 postcode). Talking with my regular courier, so take this as anecdotal rather than cited, there are apparently courier representatives (brokers) at some major depots that bid on the packages as they are being readied: presumably, lowest bidder wins the business. I also use Prime for earning download credit. I can select a slow delivery option for my order [0] if I'm not in a hurry, and get 1GBP as a kickback. In November and December, this increases to 3GBP. Over the year, I typically place 200+ orders (some for me, some for clients) and most are slow delivery. This effectively means I make money on the Prime subscription, and I can expand my Kindle library without spending real money. At any given time, I have about >5GBP in digital credit [1] - there are supposed to be expiry dates on it, but I've never fallen foul of it.
