We LOVE Cardboard Diamonds! My ND daughter can sometimes get wrapped up in what she is looking at and take forever to decide or doesn't fully communicate that she is hoping to trade to lower the price on something but all the employees have been AMAZING with her. If the store is busy she knows she has to be patient but we have never had a bad interaction since we started going there. They always have a great selection and their prices are competitive with others. They have always been fair with our trades.

Love this store! Been going here for a little of 6 months now and this is the spot to go for deck building. They do a great job with trade/buying cards to maintain a healthy stock that I love to shop, trade, and buy more and more cards to build my One Piece deck. Staff does a great job balancing between people playing TCGs and people shopping/trading and are always super friendly!!!

The person who helped my boyfriend and me was very patient and helpful. They had a great selection of cards, many of which were quite beautiful and very reasonably priced. It seems they price their cards based on the lowest sold listings on eBay, which could explain the pricing. Overall, I had a great experience and will definitely be returning.

Not sure what’s up with the negative reviews, but I’ve always had positive interactions coming in with my family. They can get busy because they have a great selection and prices, never had a problem waiting my turn while other customers are being helped. Prices are lower than some of the massive shops, everything I’ve purchased has always been at fair market price and without having to pay for shipping vs ordering stuff online.
