While they may not "sell out," or don't have the best of quality, Tamashii Nations continues to produce more product because consumers continue to purchase them. Which, while I may be mistaken, is what I believe Hydeous was getting at with his post.
Yeah, I've noticed that as well. When I went to the Tamashii Nations World Tour in New York City, I noticed that Bluefin was selling Vegito and had quite a few of them. I kept going back to the event and they were completely sold out by the end of the weekend. I'm not sure if it was due to him coming back for a brief moment in Dragon Ball Super or that event introduced the line to new consumers, or quite possibly both, but it was very surprising to see him sell so well.
A friend in San Diego also said that Beerus, Whis, and Super Saiyan God Super Saiyan Vegeta were selling well during San Diego Comic Con. Super Saiyan God Super Saiyan Goku surprised me when I saw how much he was going for lately. It could be due to Dragon Ball Super's popularity. It seems like more than a coincidence that the older releases that are selling well happen to all be part of Dragon Ball Super (or Buu Saga since that's airing also.)
Yeah that what I meant.
Only DBZ and possibly Star Wars line that has folks buying multiples and sometimes dozens of the same figure. No ones buying naruto or Kamen riders like that. I've seen posts of a collector buying 6 gohans, or 3 sdcc son gokus.
