A big part of why it's good is that it's familiar and you're probably already registered.
But that was years ago, now the address is already registered and it's not something I remember every time I shop there. Instead, what I experience every day is a very streamlined checkout process (the only small frustration is that the option to "group shipments into a large shipment" seldom appears now. The other day I bought two little boxes, identical except for the color, for about maybe €9 each, and they shipped separately, which is a bit jarring).
Many other online stores are all shiny with nice slogans but if you have a problem and need customer support then good luck.
This is also visible in the fact that Amazon makes it simple to cancel an order before it ships (just one click) and that they don't charge until an item ships.
Even when 3rd party, like shipping, messes up.
Many stores treat the package someone else's problem as soon as it's out of their shop. Amazon seems to be the only one who cares about the tracking number too(this may vary country..).
1)Keep the item, no charge (small ticket price item delivered twice by mistake). 2)We've refunded you, and for your inconvenience we've topped up your gift card by £5. (delayed delivery so cancelled).
Most other UK stores: 1)Please jump through several hoops and go an hour out of way to send it back to us (at your own expense) then it's 50/50 if ever hear another thing. 2)No reply whatsoever
I don't like it that amazon is taking over everything, but it's happening because they're really good at what they do.
The other week he said they were not accepting his card so, assuming he was making some obvious mistake, I tried with my own card and found the same problem. Using another card, the same.
Two weeks later, the same problem. Yes I emailed support at the time and never got a reply?
And yes, this is also one of the supermarkets that requires 4 or 5 clicks after you have selected to checkout.
No doubt they'll be blaming amazon for their fall in sales of late.
The biggest threat I see to this though is Apple Pay (for mobile web). When sites integrate with this properly, it enables them to match the Amazon experience. No need to register or enter any details, just one fingerprint, and all done.
If there was a cross-platform payment service which integrates with Apple, Google, Samsung (et al) Pay, and then is ubiquitously employed on mobile web, now that could make a dent in Amazon sales.
The integration needs to be easy and well implemented. I've lost count of how many sites I've gone through "1-click" pay with PayPal and then still had to enter my address details again because they haven't integrated it correctly with their shopping cart.
