I need to use some Kmart rewards points in the next couple of days and I decided to pick up the Chima gorilla mech and some fillers to get free shipping. Kmart doesn't have too many options. I have narrowed down my three filler options too: 1. Republic Trooper vs sith battlepack 11.36 and Castle Forest Ambush 9.29 total 20.65 2. Shredders Dragon Bike 24.96 3. Sith battlepack and Droidekas battlepack 11.72 for total of 23.08 Which should I go with?
