Buying rings online

Has anyone done this? I know some sites where I found some good prices, but does anyone have actual experience with any sites?
I am looking to buy a white gold plain band for me, and a titanium band for FH.

Any recs would be helpful! I have bad luck with Ebay, so that's out.

TIA!@

I ordered my bands from blue nile and I was really happy with their service.
We had priced the same rings at a couple of jewelry stores and blue nile was at least 35% cheaper.
