* Once upon a time, 2-day shipping was free and next-day shipping was $3.99. Then they raised the price if the next day happened to be Saturday. Now, next-day shipping varies depending on the item and is often unavailable. It's never less than $3.99, though. 2-day shipping is rarely shipped via a 2-day shipping service; often they drop it in the mail and hope for the best. (Also, why even bother charging me $4? Just make next-day shipping free and charge $4 more for the thing.)
* Various unreliable courier services end up doing a good chunk of the deliveries. UPS, Fedex, and the USPS are great. I don't know how they do it, but they manage to break into my apartment building every day of the week and drop off packages without me ever knowing the details. Lasership and A1? Yeah right. I love it when they try to deliver packages to my office at 10PM. Are any office mail rooms open at 10PM ever? Ever? Nice try. (Does Amazon even use A1 anymore? I remember finding a bug in A1's website that disclosed the name and address of all their customers. Emailed security@amazon and security@a1. Heard back from Amazon that they fixed it. Never saw another package from A1. Maybe A1 just rebranded as Lasership. I really have no idea.)
* Add-on items. Need I say more?
* Every time you order something from Amazon, you get a stupid interstitial about how you can opt-in to receive email about streaming a bunch of B movies and flopped TV shows at 160i resolution via your Flash player. No thanks, Amazon. You're a physical media store, not Netflix! It's cute that you're trying, though.
Finally, while I'm ranting... it's weird that amazon.co.jp and amazon.com don't share my credit card information and address. Would also appreciate Prime for amazon.co.jp, but I know that's never going to happen.
