just thought a compilation post would be good.
 
First two are part of the mane six covers, which would be the basic set you can buy; or purchase in a box set
 
Third seems to be a subscription variant cover http://www.midtowncomics.com/store/dp.asp
 
Fourth, may be a basic set like the main six covers
 
Wonderbolts third eye comics
 
Derpy = Midtown exclusive http://www.midtowncomics.com/store/dp.asp
 
Lone Star comic cover, for the Lone Star store
 
 
11 variant covers so far… still isn’t as much as IDW’s Ninja Turtles or Godzilla’s first issues though
