DC can do some pretty nutty ratio variants, such as the completion variants. These variants retailers have to jump through some pretty steep hoops to get them. DC is releasing a 1:150 Batman Fortnite Zeropoint #6 Completion variant (and we are going to tell you where to get them cheap too)
So the low down is retailers had to order 25 copies of 1-6 Premium Cover to qualify, making this one a 1:150. Tfaw has the Batman Fortnite Zeropoint #6 Completion variant for $19.99. Most retailers may have not ordered 25 copies of the premium, instead looking to capitalize on the cheaper regular cover, and therefore, would not have qualified.
