Medicom's prices are for the most part static so I doubt this will be any more than the typical figure from them.
Also just in case you were unaware, the "Big Three" do not exist. That's a term made up by Amerians, but it in no way is actually accurate. For example, a few weeks back Bleach had one of the worst overall weekly rating in the Weekly Jump magazine that week. One Piece and Naruto are not always within the top three either. There is no true Big three of Weekly Jump and if there was, the only one of the three that would be included would be One Piece and, when it is actually being serialized, Hunter x Hunter.
I wouldn't say it's a term made by the Americans as it's something I've seen in Bakuman when it started in Japan. I do know it's not always the case of them being the top spots but they were still referenced as the "Big Three" not to mention they regularly have the title pages, colour pages and alike.
