I managed to stop into Toys R Us earlier today since I heard that the series four Collectible Minifigs are showing up in stores now. I guess I got lucky since the associate I talked with said they got their shipment of series four the previous day.

I ended up getting a Musketeer, the Hazmat guy, an Artist, the Garden Gnome, and the Soccer Player. I felt almost all of the other figs, but I had to pass on most of them since I didn't want to spend $50. The only ones I didn't find were the Frankenstein and the Mad Scientist.
