The first issue of the month, AMZ #552 fell below the 90,000 mark. The last iss, #554, almost dipped below the 81,000 mark. If the current trend continues AMZ may fall under 80,000 per month and sale worse than than the pre-OMD issues.

Without the BND storyline boosting it, I believe sales would be a lot worse. IMO.

was also crossed over. Now,I started with Amazing Spider-Man #18 which was a continuation of #17. It took me years before I got that issue. Marvel has always been serialized, that's why years ago, they started doing Recaps of the previous issue at the beginning of the comic. They still do that so that the new reader can have an idea as what preceeded. Based upon what was the flag ship and major seller, I'm sure the suits at Marvel felt that going with Amazing would allow them to consolidate sales. There will and still are, mini series, one shots etc but at least for the forseeable future, consolidating the title with an ALL star writer and artist line up, makes better marketing sense.You have to remember, its the MASS market that makes things happen now adays, not the fan boys and girls. I know that sounds like we're being kicked to the curb but the truth is, Fan boys complained about Special events like Civil War and the Death of Capt America but that's what drove sales for Marvel big time last year.
