Hello to everyone. Today I'm going to do a very good review on "Grand Slam Tennis". To give you a brief introduction to the online store, "Grand Slam Tennis" is a family business and has been in business for over 40 years. Jim Donnelly has been the proud owner and operator of Tennis Emporium & Grand Slam Tennis for over 42 years. Grand Slam Tennis opened in 1986 after the birth of Jim's youngest son, Chase, who is now his business partner. An owner can always be found in either location. Chase runs the Commack Store and Jim runs Miller Place. You can shop safely on this site. By the way, the site accepts payments with Mastercard, Visa and paypal.
