Tiffany & Co In Charlotte – How Big Is The Selection?

I am planning on making a few hour drive ot the tiffany & co in charlotte to look at engagement rings. Reaching someone helpful at the Tiffany & Co customer service phone number is difficult at this time of year, so I was thinking of driving to the actual store. About a week ago I did talk with someone from the national office on the phone who described some engagement rings within my budget. Does anyone know if it is likely that they will have a good selection of rings at the actual store in charlotte?Tiffany & Co In Charlotte – How Big Is The Selection?
