Grand Slam Corner Inc

Ken S. At North Babylon location was absolutely knowledgeable and extremely helpful with my purchase. The customer service is top notch. They really do care about their clientele. Whether you're looking for pokémon, basketball, baseball, football or and thing collectable related this is the place. Again, thank you for a great experience.

I drive 30 min both ways each time to come here and my main reason is the staff. The guys are very welcoming, friendly and knowledgeable. You can sit and rip packs open , look through their loose cards and they have one of the largest selections of cards in the area from TCG, Star Wars, UFC and all sports in between to single raw and graded cards. I definitely recommend this for collectors or card players.

This place is awesome!!! Went for a meet and great with an MLB player!! My son got to take pictures, get autographs and so much more. The place was so clean and bright. Plenty of seating to sit back and relax or just rip into our newly purchased baseball packs. Do not drive by this place without stoping in to check it out!!!

My family loves coming here on Saturdays! The staff is knowledgeable and so friendly. Grand Slam always has inventory at good price points. We go out of the way to come here and will continue to.
