In what ways?

They make it difficult to return inexpensive items. It's happened two times when I have been a Prime Member. Once, they sent me the wrong model radio. It was only 10 dollars, but it's the principal of the blah. When I tried to return it was not just a click--I had to call, and the number was actually busy.

Plus--that two day shipping--works great for their items, but it's hit, or miss with resellers.

I've only returned a few items over the years, and I've spent a lot of money with them. I tried to return an $11 product last year. They just refunded me the money and told me to keep it. I had a $35 product stolen off my doorstep once (empty box left behind). They shipped me a new one, no questions asked.

You can also do a web chat, which is a lot easier then telephoning.
