Buying
There are many ways to acquire comic books. The easiest comic book to find is going to be the newer ones. The most likely source of comics is to find a local comic book store and find what you like. You can also find new comics at large, one stop shopping, stores, toy stores, book stores, and some corner markets.
If you are looking for older comics, you also have many options. Most comic book stores carry some type of back issues. You can also find older comics on auction sites like Ebay, and Heritage Comics. Also look in newspaper ads or online posting sites like www.craigslist.com.
Selling
Selling your own personal collection can be a difficult choice. If you get to that point, knowing when and where to sell your comics can be key. The first thing you must know is the grade (condition) of your comics. Once you do, you can be on your way.
Next you need to decide on where to sell your collection. An obvious choice would be a comic book shop, but they will not be able to offer you what they are actually worth, as they need to make a profit as well. You can also try to sell them on auction sites, but be warned, you need to make sure you are very forthcoming about the condition know how to protect your comic books during shipment.

Protecting
There are generally two basic camps when it comes to protecting your comics. The entertainment collector and the investing collector are those two. The entertainment collector buys comics just for the stories and doesnt really care about what happens to their comics afterward. The investing collector buys comic books just for their monetary value.
Most of us fall somewhere in the middle, buying comics for pleasure and wanting to protect their future value. The basic protection is putting them in mylar plastic bags with slim cardboard boards to keep them from bending. After this, they can be stored in a cardboard box designed just for comic books. All of these can be bought at your local comic book store.
