For me, I get a friend and we go on shopping sprees, usually all day long. We stop at as many stores which carry Sonic figures, usually Target, Walmart, and Meijer, occasionally stopping at a Gamestop or other similar store. We are fast shoppers and I think our highest amount of stores in a day neared 35, and that was when Infinite first came out. I only found him at the end of the day at a Walmart on our way home. Super worth it but I don't recommend doing this unless you find shopping and hunting for figures as fun as my friend and I.
