I struck out at the first TRU I went to but lucked out at another, ended up with a whole set. =) I didn't have a print out sheet on me so I had to painstakingly do it one by one. What I had noticed (might make it easier for some of you) The last few bars on the barcode are either || or ||| and each one has 8.
Skater, Cheerleader, Ninja, Spaceman, Cowboy, Tribal Hunter, Wrestler, & Magician all have || at the end.
Deep Sea Diver, Robot, Forestman, Zombie, Crash Dummy, Clown, (The last 2 are tricky they look like || but are separated by a small gap) Nurse, & Caveman all have ||| at the end. This should make it easier if your only looking for particular ones with having to look at all of them, at least breaks down the search from 16 to 8 when broken down.
While I was at TRU they had a lot of the new summer sets Kingdoms, Atlantis, City, World Racers (really cool reminds me of a legofied version of Mad Max), and Duplo Cars. I bought a few of the Kingdoms Outpost Attack 7948 and Prison Rescue Carriage 7949.
