Pulled the one piece tcg op13-118 red manga! Had to work the next day so the only time I had to drop it off was after 5. Thankfully they are open late enough! Im not a collector by any means so I called them loaded with questions about getting it graded.

★★★★★ Christopher, Dec 2025

I’ve known Zack, the owner of World’s Greatest Card Shop, for a few years now back from when he worked at another sports card store and I couldn’t be happier to see him running his own shop here in Westport.

★★★★★ Sean, Oct 2025

I've been collecting for a good amount of time, so finding a trustworthy card shop is important to me. Zach (the owner) is one of the most honest and friendly guys in the business. He takes the time to help you find what you're looking for, and he’s always a pleasure to work with.

★★★★★ Justin, Aug 2025

Employees were super helpful and kind, great selection of singles and sealed products and reasonable pricing as well. I also love how inclusive they were to the kids/teenagers that came into the shop. Definitely a local store worth supporting and I can’t wait to come back as I grow my TCG collection!
