Cardboard Diamonds has been consistently friendly, fair, and welcoming. They’re incredibly well priced for singles trade ins and buying, giving super real numbers on everything I’ve sold. The amount of product they have on their shelves beats everyone in the Tri-Met area.

★★★★★ Kian, Dec 2025

After visiting 5 other local card shops, this has to be the absolute best one I have found in the Portland area. The staff are incredibly knowledgeable and helpful. The 10% off discount for cash is WONDERFUL, especially with an ATM right around the corner at the 7/11.

★★★★★ Max, Apr 2026

I love this place. They had soooo many cards we were looking for. Prices aren't marked as they will price everything out for the current market value, which I LOVE. I don't know the kids name who was helping us but he was so patient after I kept asking to pull card after card from the same case.

★★★★★ Gina, Aug 2026

Super fair shop, probably the best in the area for singles and sealed. They carry magic, pokemon, one piece and more. I played the final fantasy prerelease there and I visit frequently to pick up singles for my commander decks.
