I was just able to purchase the Mamba Forever edition for $9.99 so If you were interested/missed out, it's still there
If for some reason it still says unavailable, try refreshing a couple times.
trying to find an official source explanation as to why Turf Masters was delisted. I'm hoping to acquire most of the KoF/Fatal Fury games as they hit sale but a sudden delisting has me nervous
loving the Halo talk, can't help but wonder why Reach hasn't gone on sale in the marketplace
picked up Batman: Return to Arkham $5, Injustice 2 Legendary Edition $18, Mortal Kombat XL $5, Final Fantasy XIII $8 so far
