I've been a prime member for years and buy a lot of items from/through them and I've never had an issue. From TV's to cameras, computers, anything. If you need a return they really are awesome as well as for replacements.
Tax is a new issues for many Amazon customers so you should take that into account as nairfotografia posted, B&H is really good too and there are many others.
If you look at the Amazon price you can see many small shops selling through the Amazon stores as agents and the price will show you it is Amazon, Abe's, or any other store selling the camera or item.
I got mine for 3299 from Dell but I called in for the price, the web had 3499.
