Amazon website complaints that have bugged me so much I started a Chat with them... there is no site feedback link that I can find.
1) Your Orders summary page - this page lists insufficient summary info. It does not show order number or the actual amount paid, but rather the items' individual current price. That is of little use for an Order History/Summary page. I have the Amazon credit card that gets me 5% back and on the bill it lists all orders as just the order number, cost, and retailer name like Amazon.com*MH2NO Amzn.com/bill WA. So if people want to compare their bill with what was purchased on the site to see if everything is correct in a given month, they would have to click into each order on the Your Orders page to even see the order number. I had over 15 orders for this last bill, which makes this completely tedious. Right now, the order summary page is only good for seeing what shipped and when. There is also an Order History Report (not easily accessible) which will list order number and segregate each order by line item but I'd have to add each item's total for a given order number - also tedious.
2) Your order has shipped emails - these emails are worthless other than telling you *something* has shipped. Here they list the order number but don't list the items for whatever reason. From my recollection, every other website I've used to buy anything shows you what item you purchased when it sends you an email it has shipped. I order frequently enough that having to click on the button after clicking into my email to find out what has shipped is an issue. It could easily be added to the info on the email instead of just listing an order number. You also have the issue of sometimes only a partial order being shipped, so just show the damn items that have shipped instead of saying only part of it has shipped. What also doesn't make sense is that the same email will show you "Buy It Again" and actually show you images of what you've purchased in the past. Show me an image of what just shipped then, for fuck's sake. Both perhaps a marketing ploy to get you to go to the website...
I'm not some baller ordering expensive things - they are frequently like $10-$25 each order. I like that Prime affords people the freedom to order randomly as needed for no extra shipping cost each time which is exactly my use case. But these are glaring user experience issues that the largest retail website in the world being around for 20+ years should not have. I'm a web-app-dev'r by trade and after working out all the bugs, the next important thing should be to put yourself in the user's shoes. The chat representatives were very receptive to these and said it would be implemented but I'm not hopeful...
