So far, I've gotten an iPhone, a bottle of Clive Christian perfume (which I promptly sold), and an Angelina Jolie's hairstyle and earrings - which is a BP item, 19 charm / 9 pop. That's one fewer pair of mocha suede boots I have to buy.
This collection thing is frustrating. The items will.not.drop. Plus, I've earned platinum mastery in all the out-of-town events, so now I will have to go back... grrr.
