Great communication + General Experience

Great communication, very straightforward. I was worried about sending my cards because of course everyone's collection is important to them, but don't have any fear sending to Oliver and Big O he'll transact the business exactly as he says. Thanks

Excellent communication with the store…

Excellent communication with the store owner. Great support starting from a lightning-fast quote with an unmatched percentage rate, followed by shipping instructions (fully paid for by the store—and I sent 4 packages from Poland, over 900 km away!). Fast evaluation of the delivered cards—over 11,000 processed in just a few hours. The final offer was even better than expected. A responsible and accommodating store!

Quick and trustworthy service

I wanted to sell my collection of 3,000+ cards quickly, without having to deal with multiple transactions. Oliver was quick to respond from start to finish and was open to some small negotiation. I received the money transfer less than one hour (!) after the package was delivered to Big O Cards. I highly recommend!

The best way to liquidate a collection in a painless manner

I can only say good things about Big O Cards. I contacted Oliver on a monday and 3 days later I was getting paid. The whole process was smooth, transparent and Oliver was always open to any question.

If you have a large or small collection of cards that you need to liquidate in a fast, painless manner Big O Cards is the best alternative in Europe.

A perfect selling experience

I recently sold 6 duals to Oliver and the experience was perfect from A to Z. He appraised the cards I had fairly, offered a decent amount of money for them, explained the transaction procedure in detail and helped me with process of sending them from the Netherlands to Germany.

The communication was fast, smooth and pleasant. I can recommend this business to everyone!

I sold a large amount of cards twice to Big O, and in both instances the communication was smooth, the conditions of the offering were clearly laid out and the payment was swift after receiving and checking the cards. I would gladly do it again and recommend Big O if you need to sell any amount of Magic cards.
