N.C. Gen. Stat. § 25A-6: "Seller" defined.

"Seller" means one regularly engaged in the business of selling goods or services. Unless otherwise provided, "seller" also means and includes an assignee of the seller's right to payment but use of the term does not itself impose on an assignee any obligation of the seller with respect to events occurring before the assignment. (1971, c. 796, s. 1.)
