Combo Edition" of their new 52 comics, featuring a slightly altered cover of JUSTICE LEAGUE #1, it would be a safe bet that SUPERMAN will also receive the Combo treatment.
Combo editions will be polybagged with a redemption code for a digital download of the issue upon purchase (which means that the comic book store has to active the code - similar to the way gift cards only works once activated?). Prices are yet unknown, but I am hoping it is no more than $1 extra than the Standard version. The cynic in me thinks it will be closer to $4.99.
I still think the digital version is priced too high - DC wants you to pay $2.99 for the digital version (which costs virtually nothing to distribute).
UPDATE: From dcu.blog.dccomics.com, prices for the Combo Pack of JUSTICE LEAGUE #1 will be $4.99 ($1 more than the retail price of $3.99). Regular digital version is still the same price as print edition, $3.99.
