Midtown Comics, which his located in New York City, have a special sale for the month of June. Customers can use the secret codeword "LANTERN" to get 25% off of all DC Comics. The sale is particularly attractive because it applies to both current and back issues. To the best of my knowledge, this is the first time that Midtown Comics is offering a sale on new issues. Usually, these discounts only appear on their in-store sales. So enjoy the sale and save some bucks.
The codeword is not case sensitive. When you go through checkout, make sure to type in the codeword and click "Activiate."
