Visit www.marvel.com/comics. There, you'll be able to shop for both print issues and digital copies that you can read on your computer or portable device. Marvel's online comics store is unmatched when it comes to selection, since all of the titles come straight from their own archives. Digital comics are generally more affordable than print comics, but have no collector's or resale value. If you tend to spend more than $10 per month on comic books, it may be worth your while to sign up for Marvel's premium subscription service, Marvel Unlimited. With Marvel Unlimited, you'll get access to over 25,000 comics for $9.99 a month. Sites like Amazon, Barnes & Noble, and Powell's can be good places to start if you're in the market for a specific trade paperback, collection, or one-off. For single issues you may have more luck browsing the web stores of well-known comic shops. Midtown Comics, Mile High Comics, My Comic Shop, and Newkadia all have huge selections and competitive pricing. The prices at online retailers are similar to those in-stores, though shipping can add a few extra dollars to your total at checkout. To keep shipping costs to a minimum, it's best to batch your orders as much as possible when buying online. Select the "Books" category, then use the subcategories or search bar to narrow down your search. Collectors often use e-commerce sites to unload titles they no longer want, so you never know what gems you'll come across. The titles available on Ebay and similar sites are constantly changing, so be sure to check back later if you don't find what you're looking for the first time around. Log into Facebook, then navigate to the "Marketplace" link on the left side of the home screen. Enter "Marvel comics" into the search bar to pull up a list of comics and other related merchandise. Unless you change the location of your search, you'll only be shown being listed in your own city, which makes it easy to get in touch with the seller and discuss purchase and pickup options. If you're using the mobile Facebook app, the Marketplace link will be the third one from the top when you select the menu tab in the bottom right-hand corner of the home screen. Most of the comics on Facebook Marketplace are either new releases or second- and third-hand issues that may not be in the greatest condition. Occasionally, you may also catch some rare and highly-sought-after items going for a bargain.
