Prices seemed to be in-line with internet prices, which is always great to see. Supporting a local business + not having to pay shipping/wait for shipping is a huge win in my books!

Kevin was super friendly and he sold a variety of Pokemon collectors cards - graded, non graded cards, Japanese editions and more. Rob was extremely helpful and guided us to different areas of the shop. Anastasia's Collectibles is the main collectibles seller at the shop. I've never seen so many funko pop characters in my life! The walls were covered and organized in such an aesthetic way. There's some funko pop characters that I've never even seen before like a snowman Darth Vader! They also sell an assortment of Disney collectors items like purses, backpacks, charms, keychains and more. Mr collectibles is another seller that offers items for your little ones like needo's, butter squishier, squishmallows and limited edition plushies. I even spotted some unique comic books too. This shop offers so many different collectibles and there's something for everyone! Great customer from the employees. Pricing for the items are also very reasonable. I love that they have a variety of items. Definitely check it out whenever you're in Fullerton or if you're looking for some special collectors items.

He definitely made the whole experience enjoyable which is why I give this a 5 stars If you're in the area, definitely check out this card shop and ask for Robert. He's awesome!

I have heard tales about this place. I heard it used to be a great spot until the new owner took…read moreover. He is a total sleeze and gives big insecure loser energy. I literally just started going because it was a convenient stop on my commute. But on my second visit to this place, I witnessed an incredibly uncomfortable interaction at Card Addiction. I saw a similar story on google reviews and it may be the same incident, but I also wouldn't be surprised if this has happened multiple times. I saw the owner publicly accuse a customer of stealing a $0.50 die. The customer earnestly apologized and tried to explain the misunderstanding. The owner would hear nothing of it and instead began repeatedly calling them a thief and spewing such hateful energy at them it made me sick. Everyone watching could see that it was an honest mistake, yet this sorry excuse of an owner doubled down on this narrative he had in his own head. It was so off puting as a customer to see a representative of a business in our community failing to show any kind of professionalism, common sense, respect, or basic decency. No business owner should treat customers with that level of hostility over an honest mistake, much less a 50 cent mistake. Publicly humiliating someone over most things is generally distasteful and an in this case an abuse of power. Buyer beware for this establishment. The other post on Google got a response where the owner once again defended his disgusting behavior and doubled down further by going as far as to accuse the person who posted the review a theif as well. If this review isn't proof enough, then the lack of remorse, humility, and most importantly accountability in the response to feedback should be the nail in the coffin for this owner.

First, I will list all the facts that I have experienced this past weekend (August 22, 2026 and…read moreAugust 23, 2026) at Diamond 9 Sports and the days leading up to the event. I will save my opinion at the end of what transpired. Timeline of Events Friday August 7th, 2026 Sign ups for One Piece Card Game 4th Anniversary Event (OP-17 Release Event) for Diamond 9 Sports: Saturday, OP17 Prerelease (Saturday August 22nd) & One Piece Card Game 4th Anniversary Event (OP-17 Release Event) for Diamond 9 Sports: Sunday, OP17 Prerelease (Sunday August 23rd) made available on the Bandai TCG Plus app. I successfully signed up for both events at $40 each Both events format is One Piece Card Game (English) - Sealed (Sealed format: 6 Packs (each participant should use the same number of packs.) After opening 6 packs, players build a 40-card deck, and a 10 DON!! card deck. (Source: https://en.onepiece-cardgame.com/pdf/tournament_rules_manual_op02.pdf ) Friday August 21, 2026 10:01 AM Received notification that the event has changed to Constructed format where there will only be 3 packs given out. The cost of the event remains $40. By this time all other events from other stores have filled up. Saturday August 22nd The event's format remained Constructed, however Entry was reduced to $10 and we received only 1 OP17 Booster Pack along with the promotional materials (OP17 Special Don!!, Rainbow Luffy + Luffy Promo, OP17 Release Stamped Promo Pack). Prizing (Gold Stamped Luffy) was given out to the winner. I paid this event in cash. Sunday August 23rd The event changed to Saturday's format: Constructed, Entry at $10 and we received only 1 OP17 Booster Pack along with the promotional materials (OP17 Special Don!!, Rainbow Luffy + Luffy Promo, OP17 Release Stamped Promo Pack). Prizing (Gold Stamped Luffy) was given out to the winner. I paid for this event with my credit card as proof of transaction. Opinion and Review I have been coming to Diamond 9 for a few months for their events. Thought their pricing was fair and the store owners were nice enough. That being said, how they handled this event felt very bait and switch. They advertised this event as $40 where you would get 6 booster packs. In the days leading up to the event the price and format changed (which went to $40 for 3 booster packs to $10 for 1 booster pack). This isn't an allocation issue. As Diamond 9 received their allocations of One Piece cards for this event. They just simply reduced the number of allocation of the booster packs to the players who signed up and kept the difference to sell at market rate. I agree that it is the store owner's right to change the price of a product when it fluctuates with the market but to change the format and the price after people sign up only to get notification of the format and price change the day before the event is simply bait and switch. I will not trust Diamond 9 for any business in the future as their pricing of events can change.
