Marvel is opening up its massive vault of digital comics for only 99 cents this week to coincide with San Diego Comic-Con. A subscription to Marvel Unlimited — which offers immediate access to over 13,000 comics — normally runs $9.99 per month or $69 if you pay for an entire year up front. But Wired reports that for this week only, paying just under a buck will get you a month's worth of unfettered access to Marvel's universe. There are some limitations; you can store a maximum of 12 comics on a device for reading offline, and there's usually a wait of several months before new issues reach the service. (Marvel isn't trying to put your local comic book shop out of business, after all.)

But there are also perks that come with reading on a screen instead of paper, including original, made-for-digital stories. So if you're headed to experience the Comic-Con madness in San Diego, this could make for a great way to brush up on your superhero expertise — and there's been some huge news lately.

Update July 23rd, 4:40 PM: The article originally stated that Marvel Unlimited is only available inside the US. In fact, it is available internationally. Only the Marvel Unlimited Plus service is limited to the United States. Sorry for any confusion!
