With Amazon, you can indeed save some money on shipping for lower priced orders and the free shipping minimums tend to be lower. Amazon offers 4x6 prints for $0.09 per pic, which is a bit less than the Shutterfly norm. At the same time, however, you can get photo books for $15.99 at Shutterfly while they are $19.99 at Amazon. Ultimately, the best price depends on what you are looking for as well as currently clearances and sales at either retailer.
