low prices in USA e-stores

Hello, i need an advice about buying TT beyblades in USA. The seller has almost 4000 positive feedbacks, but i can't get why his prices are lower than every japanese e-store! The average is -40/50%...
he could be getting it directly from China or Hongkong or Taiwan. much cheaper.
I thought the same, ordered 4 beys, turns out they were "Rapidity". Completely BS. I guess they are fake/counterfeit. Careful buddy!
