As titled, this hype doesn't last forever! Some of us have watched Captain America Civil War more than a week ago. Next week, I may not remember how some of the heroes' costumes look like in the movie. The week after, I may not remember which team I was on. A month later, I may post something silly here asking why Hulk Civil War costume hasn't hit the store!
Seriously, the pack will sell on its own. Don't worry about it. It is the hype that needs to be capitalized fast. Waiting any longer I may well wait for the next 50% costume discount sales, which will come eventually no doubt. Some of us have already got our mind set on X-Men Apocalypse, which is just round the corner.
Great job on the new Civil War costumes by the way. Most of them are stunning. Who did Scarlet Witch costume? That is top notch. Top, top notch.
