I have decided to be a helpful person right now, if you go on comixology right now there is a sale for the current era of x-men books, the first two volumes of most runs and the first volumes Cable, Fallen Angels, Hellions, X-factor, & Wolverine and the Giant Size X-men collection all of which range from $3.99 to $2.99. If there is a series you have not read yet or something you have been waiting on because of price I say go now.
