Yea it's pretty awful. They also by default select a faster shipping method which costs $6.99 (most of the time per item, sometimes multiple shipping charges for the same order). Every checkout I have to go through:

1. no, I do not want a prime membership for $1.99 for 1 week

2. no, I want free shipping on these items (careful check if the order is split up in multiple shipments)

3. no, I want free shipping on this item.

8 out of 10 orders my stuff arrives earlier than the paid shipping option offered during checkout.
