Star Wars tax? What Star Wars tax? First of all, that makes no sense since 488 pages for $34.99 is right in line with the fairer of Marvel's prices. If you want to compare it to the Dark Horse releases then it would be a Marvel tax, but even then comparing it is stupid.
This book costs $.07 a page while Dark Horse's release of the same material was $.06 a page and Dark Horse's release wasn't as complete as this one. If the per page price was kept and it was released at 488 pages the cost would be $29.28, less than six dollars cheaper than Marvel's release. And Marvel's release is in the normal comic trim rather than the midget mass market trim DH uses. If you were to buy all of the stories in this volume in Dark Horse trades you would have to buy three omnibuses (11, 12 and 20) and all six trades of Star Wars Tales. Here the stories are collected in chronological order which is worth the extra $5.
