I went to Meyer's jewelers over in GC. They have a 10% coupon on their website that I always print off before I go. Paid a decent but not crazy amount for the ring, but I felt comfortable doing it. We waited a little too long on ordering the wedding bands though. They had them shipped overnight to the store and mine etched with the date for nothing extra. I'm sure most would have done similar, but it's always nice for them to do that stuff.
I've been back three or four times since to buy various jewelry for my wife and have always had excellent service.
Like others have said, make sure that you feel comfortable buying from whoever you go to. Shop around if you need to.
