One Punch Man sold 13,289 copies in week 1 (the week ending in April 30th, 2017), all of which were BD/DVD combos. It’s not a surprising figure, given the high level of popularity the series enjoys in the US. Source here, photo evidence after the jump.

Digimon tri’s release week data will be coming out soon. I’m waiting with baited breath, hoping for an appearance in the top 20. It’s going to be close, and depend heavily on thresholds.
