I don't know about cameras, but before we went out at the beginning of this month, I ordered a GPS from Amazon.com and had the package delivered direct to my hotel. This was waiting for me to pick up when I arrived, and I paid £106 in the US rather than £180 in the UK. I only went ahead because the product had a worldwide warranty, so you'd need to confirm that before you go ahead. Another point is that, by ordering on the internet from a US internet supplier, you don't pay the sales tax which you would if you bought it over the counter. It's definitely worth looking into!
