Much like a tattoo, a comic book is professionally inked, tells a compelling story, and can occasionally be sold for a tidy profit. Dive into a pictorial world with today's Groupon: for $7, you get $15 worth of comic books, action figures, and more at Powers Comics & Collectibles. Today’s Groupon expires in three months.

Powers Comics & Collectibles transports pen-and-ink proponents to new realms with a large selection of current and collectible comic books, graphic novels, action figures, posters, and other memorabilia. Action figures range from comic-book characters to notable athletes known for frequenting arctic ice castles (average price of $16.99). Sought-after keepsakes from the 1950s share shelf space with newly acquired graphic novels (average price of $19.99) and comic books (average price of $3.99), with the inventory changing as regularly as Ghost Rider’s hairdos.
