Quoted from Rarehero:
Avengers Premium was announced when it came out, but if I remember correctly the full specs of the Premium weren't revealed until later. By the time they released specs/pics, it didn't get much attention as many distribs still had Blue LEs to sell…had a tough time selling them at full price…and they weren't priced that much higher than the Premium anyway. So - I think anyone who had any interest in Avengers just got a Blue LE instead.
There have been a few Avenger Premiums for sale on Pinside…but it doesn't seem like they made that many.
So, was the Premium more limited than the LE's?
