Amazing store for pokemon in my experience. I have had nothing but amazing pulls from this store. They are always buying product behind the scenes so you never know what will be on the shelves. All the staff is great, friendly and experienced. They always have a full stock.

★★★★★ Brendon, Mar 2026

This is everything a card shop should be. A great mix of cards in all price ranges, great selection of unopened boxes to rip and the most friendly cool staff as soon as you walk in. A lot of shops are pretty vibe-y to new people, over-priced their cards and won't negotiate. My experience here was the complete opposite.

★★★★★ Jake, May 2025

My husband and I love collecting Pokemon cards. We rip them open for fun and I have my own little collection of cute cards. It’s been so difficult in the Pokemon card world lately having to fight with scalpers. Diamond Valley is the only store locally that has great product still and knowledgeable staff!

★★★★★ Lady, Mar 2025

The staff is super friendly and are very knowledgeable in everything. All the pricing is very true and reasonable, not scamming or overpricing anything. Super wide collection of everything you would want for the most part, and the services they provide are excellent. The overall atmosphere is friendly and just awesome.
