I just found out that when sims visit campus, they can return with some bonus items! I knew that they went out to get pizza, but today I noticed them bringing back black garbage bags or trash bags, and didn’t see anything come out of them. I looked around the wall and found several bonus items that I hadn’t put there! Here’s the first link I found which lists some items they can bring back: http://www.neoseeker.com/resourcelink.html?rlid=99823
Who knows where they find this stuff? My Sims brought back a radio and were dancing to it for a while and I still didn’t realize that it was new!
