Saw some people bought some boxes and opened them.Contained 4 packs of Galactic Connections,2 packs of Clone Wars(blue packing,not sure which set),2 packs of JTTFA & 2 packs of TFA series 1.Most got nothing special but did saw a few got a sketch and autograph.I would say don't waste your money,save for TLJ,IMO!!!Unless they have been out for a while, I spotted a few "Phantom Force" sealed small boxes at Walmart. They look to be extra/unsold Star Wars packs from the last 2 years or so as a deal offering.
The contents said something like 4 random sealed packs, I think 4 packs of those Galactic discs and a bonus jumbo pack. $14.88 each if I recall. I wanted to take a pic but left my phone at home.
