I was previously 0-5 with e-Pack.
I purchased one 5 card pack of 2016 Upper Deck Captain America 75th Anniversary via e-Pack for $5.99. That series is exclusive to that service.
Cool cards in that set includes: autographed Sketch cards; Vibranium Shield Mosaics made of metal; translucent Trapped Ice cards; and redemptions for Coin Cards.

Wow! I finally acquired something valuable from e-Pack! That cool card is made of allumium, and is one of the 20 Puzzle pieces from that subset.
I've listed that card on COMC for only $49.99. That's a very low price considering you'd need to purchase four $114.99 boxes to acquire one of those cards, on average!
