I use an online rewards program called Swagbucks to earn Amazon Gift Cards which I use to buy Disney Infinity Figures, Power Discs Packs, etc.
An Amazon Gift Card costs 450 Swagbucks which can be earned by watching videos, surveys, playing games, codes, special offers, etc. An average person could easily score at least 50 swagbucks daily if he/she is only OK at earning points. So that would net you a $5 Amazon Gift card every 9 days. You could see it as a free gift card or like I see it, a free Disny Infinity Power Disc pack. If you get really good at Swagbucks, you can earn a gift card for a gift card every 3-5 days.
I have gotten the following Disney Infinity items for free using gift cards earned from Swagbucks.
9 Disney Infinity Power Disc Packs
PDP Base Protector
PDP Power Disc Capsule
PDP Disney Infinity Play Zone Bag
Disney Infinity: Prima Official Game Guide
Private message me your email address if you are interested in the program, and I will send you my referral link.
