Yes, I use Amazon quite often for buying books, video games, electronics, and other stuff. Their shipping times are pretty fast, and I never had major problems with Amazon except for 1 cancelled order because of out of stock problems.
Same for me I use Amazon to search for items, and the prices. But, the prices on Ebay don't really reflect the prices at regular retail stores especially if you buy from Amazon Marketplace where the prices are even lower sometimes.
