They Stand by Their Brand

There's an old saying: it's not the fall, it's how you recover.

I'm a long-term customer and fan of Theory11, but for the first time ever I had a significant problem with part of an order.

It turns out Theory11's excellence in design and (typically) quality extends to their customer service. I went from being upset and disappointed about part of a product to being so impressed with how they handled it that I think I'm an even bigger fan of theirs than I was before, despite having had a problem!

Hats off to Mandy and the customer service team at Theory11!

Great selection of playing cards

Great selection of playing cards. Reasonably priced. Great customer service from Mandy. I would recommend to any playing card enthusiast. The collection is growing and I’m looking for more to purchase.

Boxed Set Inquiry

I reached out inquiring about an order I placed. I initially received an email with my order info, but it did not indicate shipping info or date I might receive my decks. I reached out by replying to the email I received, and received a quick response. It was very polite and provided all the information I needed. Great service!

A Wonderful Company

I am deeply impressed with this company’s customer service and with the quality of their products. They shipped my order faster than I had thought possible. Three days later, when I contacted them because the post office had reported it as delivered—but it was nowhere to be found—I was amazed by their rapid response, kindness, and willingness to help. (Our postman had left the package at the wrong address.) Once I received the item, I was elated that it actually exceeded my high expectations. I will definitely be ordering from Theory11 again.
