59 N.C. App. 677
FIBER INDUSTRIES, INC.
v.
CORONET INDUSTRIES, INC.
No. 8218SC91.
Court of Appeals of North Carolina.
December 7, 1982.
*78 Brooks, Pierce, McLendon, Humphrey & Leonard by James T. Williams, Jr., and Kathrine A. McLendon, Greensboro, for plaintiff-appellee.
Smith, Moore, Smith, Schell & Hunter by Alan W. Duncan, Greensboro, for defendant-appellant.
HEDRICK, Judge.
The defendant argues that the plaintiff must establish the statutory grounds for personal jurisdiction under G.S. § 55-145(a)(1) which reads in pertinent part:

Jurisdiction over foreign corporations not transacting business in this State. (a) Every foreign corporation shall be subject to suit in this State, whether or not such foreign corporation is transacting or has transacted business in this State and whether or not it is engaged exclusively in interstate or foreign commerce, on any cause of action arising as follows: (1) Out of any contract made in this State or to be performed in this State;
....
The defendant contends this statute applies because of the provision for "Special Jurisdiction Statutes" in G.S. § 1-75.4(2). Defendant goes on to argue that the jurisdictional standard of G.S. § 55-145(a)(1) has not been established because the defendant has had insufficient contacts with North Carolina, the contract involved was not made or performed in North Carolina and there is no nexus between plaintiff's claim and the defendant's contacts with this state. The defendant also contends that the requirement of constitutional due process has not been met because it does not have the requisite "minimum contacts" with North Carolina "such that the maintenance of the suit does not offend `traditional notions of fair play and substantial justice.'" (Citations omitted.) International Shoe Co. v. Washington, 326 U.S. 310, 316, 66 S.Ct. 154, 158, 90 L.Ed. 95 (1945).
A two-part test controls the proper determination of personal jurisdiction. First, a statutory basis must exist for finding personal jurisdiction. Second, the exercise of personal jurisdiction must meet the requirements of constitutional due process. Dillon v. Funding Corp., 291 N.C. 674, 675, 231 S.E.2d 629, 630 (1977).
The applicable statutory provision of the North Carolina long-arm statute grants a court of this state jurisdiction
[i]n any action, whether the claim arises within or without this State, in which a claim is asserted against a party who when service of process is made upon such party: ... [i]s engaged in substantial activity within this State, whether such activity is wholly interstate, intrastate, or otherwise.
*79 G.S. § 1-75.4(1). The statute which defendant argues controls the instant situation, G.S. § 55-145, is an alternative ground for finding jurisdiction. As stated in G.S. § 55-146.1,
[i]n addition to the provisions set out in this Chapter, foreign corporations may be served with process and subjected to the jurisdiction of the courts of this State pursuant to applicable provisions of Chapter 1 and Chapter 1A of the General Statutes.
Therefore, we find that G.S. § 1-75.4(1)(d) controls the jurisdictional issue in this case, and under that provision the necessary determination is whether the defendant was "engaged in substantial activity within this State." G.S. § 1-75.4(1)(d) does not, by any of its terms, require a finding of a nexus between a plaintiff's claim and a defendant's contacts with the state, but applies to "any action" against a defendant "engaged in substantial activity" in North Carolina.
In our opinion, the facts of this case demonstrate "substantial activity" by the defendant in North Carolina. Over the past several years the defendant has purchased millions of dollars worth of yarn from the plaintiff in North Carolina, solicited orders for carpet through its sales representative who maintains 50 accounts, sold millions of dollars worth of carpet to over 140 customers, purchased goods and services from more than 100 individuals or companies, provided promotional aids to its salesman, maintained a WATs line for its customers' use in placing orders at its Georgia office and given cooperative advertising funds to some of its North Carolina customers.
We further find that these facts fulfill the requisites of constitutional due process under the second prong of the two-part jurisdictional test. The minimum contacts standard of International Shoe was later refined by the United States Supreme Court in Hanson v. Denckla, 357 U.S. 235, 253, 78 S.Ct. 1228, 1239, 2 L.Ed.2d 1283 (1958):
[I]t is essential in each case that there be some act by which the defendant purposefully avails itself of the privilege of conducting activities within the forum State, thus invoking the benefits and protections of its laws.
Our own Supreme Court recognized these principles in Farmer v. Ferris, 260 N.C. 619, 625, 133 S.E.2d 492, 497 (1963):
It seems, according to the most recent decisions of the United States Supreme Court, that the question cannot be answered by applying a mechanical formula or rule of thumb, but by ascertaining what is fair and reasonable and just in the circumstances. In the application of this flexible test, a relevant inquiry is whether defendant engaged in some act or conduct by which it may be said to have invoked the benefits and protections of the law of the forum.
See also, Chadbourn, Inc. v. Katz, 285 N.C. 700, 208 S.E.2d 676 (1974).
Applying these statutory and constitutional standards, this court recently held the sufficient contacts requirements for due process were met where the defendant, a Saudia Arabian corporation, whose agents solicited job applications through newspaper advertisements, came to North Carolina to interview and hire employees and mailed letters offering employment to twenty-eight North Carolina residents at their homes. Mabry v. Fuller-Shuwayer Co., 50 N.C.App. 245, 273 S.E.2d 509 (1981) appeal dismissed, 302 N.C. 398, 279 S.E.2d 352 (1981). Also, in Parris v. Disposal, Inc., 40 N.C.App. 282, 253 S.E.2d 29 (1979) appeal dismissed, 297 N.C. 455, 256 S.E.2d 808 (1979), one of the facts noted by this court in finding sufficient minimal contacts was the defendant's listing in North Carolina telephone directories a toll free number to call in Hartford, Connecticut in the event of an accident.
Similarly, in this case, although the defendant does not have any North Carolina telephone listings it does maintain a WATs line for use by its North Carolina customers in placing orders. More than that, however, the defendant has benefited from millions of dollars worth of sales over the past five years to numerous customers and has *80 purchased millions of dollars worth of materials used in making its carpet from North Carolina industries. Despite having no offices, mailing address, or phone number, or owning or leasing real property in North Carolina, its contacts with this state can hardly be called de minimus. Therefore, we hold the defendant had sufficient contacts with this state to give our courts personal jurisdiction over it. Under these facts, by denying defendant's motion to dismiss for lack of jurisdiction, the trial judge did not violate any of the requirements of due process, fair play or substantial justice.
Affirmed.
