Where in South Carolina please? Just curious as I am headed there to visit soon
That may be where the Customer Service Reps are located. But I am pretty certain the Refurb stuff is shipped from Pleasant Prairie, WI.
As far as I know the Customer Service reps are just a phone bank. They are not located in the same place as the product (Products ship from Pleasant Prairie Wisconsin - just outside Kenosha).
Physically going to the Customer Service Center will not give you any better product availability than calling them on the phone. I would expect them NOT to be willing to deal with walk in customers
