You'd expect a company with as much revenue as Amazon would be able to afford a decent web design crew. 
 
Often I will search on Amazon for a vendor I know has dozens of items for sale on the site, and their vendor name is included in all of the item titles. Search results: zero. 
 
I will order results by "most relevant" and find that the top few results are not very relevant at all. 
 
I will order by "price: lowest to highest" and find some of the most expensive ones mingled in with the cheapest ones. 
 
The site has really gone downhill over the past year or two. They changed the reviews so that you can no longer sort them by "most helpful," which means that the "helpful" score on reviews is now completely pointless because you can't read all the most helpful reviews first. 
 
Review photographs that I click on often turn out to be dead links until I refresh the page, then they work. 
 
Always amazed how crap like this gets past quality control of a company like Amazon. 

I've had my most dreadful online shopping experience a few weeks ago, thanks to Amazon...
 
I placed an order on the 12th. When they failed to meet their own deadline, I contacted them and my order was allegedly upgraded to one-day free shipping. It was to arrive last Monday (20th), no later - they promised.
 
It didn’t.
 
Instead I received an e-mail saying my order was delayed til Wednesday (22nd), but no later they assured me.
 
Come Wednesday, no package. Of course...
 
I contacted them, spent a part of my thanksgiving eve night off exchanging e-mails with them. They upgraded me to free two-day shipping (for all the good the upgrade to one-day shipping had done). My package was to arrive... Saturday (25th). Promised.
 
I went to bed with a headache. I needed that stuff the week before!
 
Well, it didn't arrive on the 25th... At least, half of it did not. They couldn't tell what had happened - which was a welcome change after all the lies and the excuses...
 
Talking with my wife, she told me that she's had issues with two orders in the last month alone. My younger brother has been expecting a package since... August! At times, the web site says it's shipped and to be delivered within days, then it goes back to its original status.
 
Tracking  packages has become a real joke. You just cannot rely on their info as it moves back and forth and you no longer have tracking numbers.
 
It had been many months since I had ordered and I was surprised at how much they now sucked. I used to purchase 99% of my Christmas gifts on Amazon. I cannot trust them with that anymore, not after this experience. Although they did ship another order I had place earlier than expected and gave me $15 in gift cards...

For the search rant, I coded my own search approach for the website I created for a customer.  One better option is to use Google by adding "site:" (e.g., "site:amazon.com" duck expanders).
 
For the purchase rant, try to find the same item on a smaller online store that still cares about the customer.

I think half the problem is that they use the most atrocious 3rd party shipping companies to do their last mile deliveries. I don't know who does it in Vegas but here in New York they use a company called Lasership. And if you read reviews of them online, you'd wonder how in the hell they were ever selected by Amazon. They're certainly the worst delivery company I have ever experienced. 
 
What happens is that they will promise to deliver on a particular evening and then not show up. So you look at the delivery status and they claim they "attempted delivery." You know they didn't because you were home the whole time and your apartment buzzer never went off, and sure as hell nobody knocked on the door. 
 
Other times they will claim they delivered but you won't get your package. People have said they have found packages left out on the street by Lasership. My girlfriend lives in a large apartment building with a lobby and an elevator, but the Lasership guys frequently refuse to deliver to her door. They just throw the package in the lobby (there's no doorman) and leave, claiming it was delivered. Of course the packages are often stolen. But worse still is that people have said they didn't receive their package despite Lasership saying they delivered, only to see their items appear on eBay later that night. They hire crooks and lowlifes and lazy good for nothing SOB's and you cannot trust them as far as you can throw them. 
 
I once called them to complain and the long-suffering guy in the office told me that all he does all day is pick up the phone and listen to people yell at him because their packages have been lost or stolen. I called Amazon to complain about them, and the guy told me that they get thousands and thousands of complaints against Lasership but that there's nothing they can do about it until their contract expires. 
 
So there you go. Not only can Amazon not get it together to build a fully functional website, but they apparently draw up contracts which don't have some kind of requirement for the other party to actually do what they're paid for. 

Then there's this...

"He was in shock when we saw the size of it"
 
Oh dear. 
 
"his real concern was for the customers who had packages delivered by the driver after that person pooped."
 
Too right. I hope anyone upstream from this bozo burned their packaging and jumped in a bath of disinfectant. 

I started buying from Amazon in 1997 when all the company sold was books.  I've always been an avid reader lol.  I stayed very loyal in my online shopping with Amazon till this year.  Over 20 years, I've purchased loads, and loads of things.  Except this year something has happened...   This year, "Walmart," of all companies has just killed it.
 
I often find the product I want, and the brand I want from Walmart online and I find it usually with free shipping, or free store pickup, and for a few dollars less than Amazon.
 
Likely I will not renew my prime membership.
 
Just a few moments ago I grabbed something from Walmart's website for $47.  It was $69 to buy direct from the brands website.  and $52 @ amazon (I would get prime shipping)  Now the funny thing is:  Amazon didn't have the size I wanted in stock anyway.  Walmart I get free shipping, I spent more than $35, but my delivery date is not until 12/11/17 - no matter, I was in no rush for this item

And why are Netflix and YouTube recommendations so off the mark?
 
I searched for albums by the band Camel (sheesh, they made a lot of albums!). Knowing the band's name is a generic word, and I didn't expect Amazon to know I was after a band, so I made sure to specify the Music CDs category.
 
What was its top recommendation? A stuffed camel toy.
 
This is evidence that the dire predictions of AI leading to human extinction may be overstated.

I'll bet Pornhub has a more sophisticated search engine than Amazon. 
 
I've always found "recommended for you" choices to be way off the mark. The trouble is that they're making very simplistic guesses about what floats your boat based on your previous views or purchases. A while ago I bought a box of extremely cheap keyrings from Amazon (it worked out to like $0.05 per keyring or something). Ever since then, Amazon has been breathlessly shoving key related items under my face. You'd think I was some kind of key aficionado. 

 
 
Spot on about Lasership sharke. This has happened to me several times with them. My wife is home all day and and they claim no one was home when the delivery was attempted.
