This is Worrisome
that certain comics from Marvel are jumping up to $4.99 in a trend reminiscent of how some comics went to $3.99 with the standard number of story pages and a back-up strip before eventually losing the back-up strips and just costing $3.99 (a trick both Marvel and DC pulled some years back). That of course was followed by almost all the comics then becoming $3.99.
This has led to theorizing we could see average-length comics for $4.99 before too long. If you're something besides a big event such as "Secret Wars" #9 or a few other cases what I do say to such a proposal? No, just no.
Now, I'm not utterly opposed to a $4.99 comic if I feel I'm getting my money's worth. Give me a 72-page magnum opus or even a meaty 48 pages and I'll be pleased (I even don't mind the $7.99 price-point for "Island", but that's basically a massive monthly graphic novel anthology). That, or you could look at the current "Providence" comic coming out from Alan Moore and Jacen Burrows which has a very detailed regular comic and then a great deal of prose back-matter that results in those five dollars lasting me a good hour in terms of time spent reading the book (and it is simply 40 pages or so each issue between the illustrated parts and prose sections).
This isn't just a concern with Marvel and DC either. I could picture some smaller publishers raising prices because it is admittedly harder for the smaller folk to turn a profit, and $3.99 or $3.50 has kind of become the standard price-point for a comic with a few lower-priced exceptions--and when something is only $2.99 that does in fact greatly increase the chance I may buy it and give it a read. That said, when the day comes a 24 page comic is $4.99 that is the day you can basically guarantee I ain't buying that book no matter what. Oh, and let's not even discuss $5.99 as a price-point for anything less than a solid 72 pages or so.
