If you are into the hobby Grand Slam on Long Island is the number one place to check out. Me and my two boys have become big collectors over the last few years. We have learned a ton and Grand Slam has been a big part of that. We have been to all 3 locations and we can't decide which one we like the best!

★★★★★ Matt, Feb 2026

I went shopping to get started on some training cards for my daughter. Let me tell you the amount of customer satisfaction I had with your employee Dan Kelly was outstanding. Very knowledgeable on every product in stock. Most importantly he was very polite and respectful.

★★★★★ Anthony, Oct 2025

I just have to say this is one of the best card shops on Long Island, hands down. They’re super honest and transparent, which is hard to find, and they really go out of their way to help you. The guys there are seriously so kind and welcoming.

★★★★★ Rebecca, May 2026

We love Grand Slam Collectibles! We’ve been to both locations and they’re both awesome—big, clean, organized, and the staff is always super helpful. It’s such a fun atmosphere, especially when everyone around you is ripping packs and showing off their pulls.
