Amazon hides cheaper items with faster delivery, lawsuit alleges
(arstechnica.com)
This is a most excellent place for technology news and articles.
Price wise it kinda depends, but for books for example unless youre getting manga or light novels youre better off going to a brick and mortar. Seriously theres a used book store thatll order books directly from the publisher, 8 bucks for a standard book. The only problem is it has to be American published and no comics.
