I’m new to the Pokémon tcg thing so when I first discovered this shop I was honestly quite surprised. I visit more than I should and probably spend more than I should but the staff have always been kind.

★★★★★ Terranova, Oct 2025

Awesome place. Great people, ive enjoyed doing business with those guys while out there working. Wide variety of cards and collectibles. I would definately recommend this place to anyone looking to expand their collection.They are easy to work w and knowledgable in the collecting world.

★★★★★ Tyler, Apr 2026

This store has a lot of variety in merchandise. A decent selection of games and collectibles. It’s a bit hard to navigate because there is little room between displays. I love the mural in the entryway.

★★★★★ Ginny, May 2025

Was in town for a wedding and dropped by this little gem. Great selection and staff was friendly. Prices were decent and they even beat game stop on a lot of things. Check it out. Its worth it.
