Damn. I hit up like 5 Targets over the last few weeks (some of them multiple times) and not one of them would sell them before 1st May. Target made a mistake by allowing the tills to ring up the sales before May 1st. Anyway, I went to another Target tonight and cleared them out. They let me take the display box and the outer carton this time.
Exactly! The manager that wouldn't give me the box had me help her remove all the Series 9 from the pegs on the endcaps so she could put up the empty display box. Weird. I'd never found the minifigures in that store before - they were in the camping/hiking section. I don't know why. No wonder they still had dozens of Series 9 left.
Ah man, I feel for ya. The odds were well in your favor - from people's very, very rough calculations it looks like maybe 1 Mr Gold per 600-1000 packets.
