“I would like to thank Cardsone for the outstanding relationship that I have shared with them for over 20 years. I have done business with Billy May and the folks at CardsOne since the early 90's and have received top quality and service since the beginning. Out of the hundreds of orders that I have placed with CardsOne, 95% have arrived quicker than expected. Whenever you have a question or concern they are enthusiastic about helping you with fast & friendly service. I have repeatedly gotten Sports Memorabilia deals at 50% less than anywhere else.”

“I don't believe there are too many people who can evaluate large card deals as well as Bill May of Cardsone. I have witnessed his ability to look at an entire warehouse filled with cards and to arrive at a number in a matter of just a few hours.”
“Cardsone also has the ability to purchase these large deals. Their professionalism and knowledge of the logistics and financing for such deals is impressive.”
“I watched in awe as Cardsone purchased one of these warehouses of cards. They purchased the three-story deal with a minimum of haggling and to the satisfaction of both Cardsone and the seller. In fact, after this deal was consummated, the seller entered into additional management and marketing transactions with Cardsone. And this seller was noted for his business savvy.”
“I would be remiss if I did not mention the fantastic customer service that Wanda has provided. Her attention to detail and willingness to go the extra mile are exemplary.”
“I have recommended Cardsone to several owners of cards and would not hesitate to do so in the future.”

“My name is Billy from Hobbies and Supplies. I have been in the card and collectible business since 1990. I have been dealing with Cardsone for over 10 years, and even longer with Bill May.
I have bought and sold to them with confidence in that past and would highly recommend dealing with them on any business level.”

"I just received another nice lot of cards. I have bought from Cardsone a number of times in the past and have been pleased with everything I have bought. Price has been more than fair and condition of items has been right on. Keep up the good work and I will be purchasing more items in the future."
