I'm so upset right now, tried to buy the Armament VonBoom

How in the hell can I put it in my cart, immediately check out, immediately pick shipping method, and begin entering my card info and LOSE IT???

YYE took it out of my cart as I was entering credit card information, there was no hold, I was not sitting on it, I grabbed it and checked out, we are talking about less than 60 seconds from the second it went live, and it was taken out of my cart as I was entering the card information.

Please explain to this college educated 44 year old gentleman how I was not able to buy this yoyo?
