Well according to the NYC store there is bonus material from Charlie's vault. I presume it's the three tracks on the B side.
Actually it's more than that. The original 83 pressing only looks like it came in a 7" with Soldiers and Howling Furies.
The new one is a 12" with
SIDE A: “Soldiers Of Metal”, “Metal Thrashing Mad”, “Howling Furies”
SIDE B: “Anthrax”, “Panic” “Death Rider”
If you can get it for $14 it's not so bad with 6 songs, (how good those songs will be given they are from the vault remains to be seen), but yeah the prices for anywhere that requires shipping is a bit far fetched.
