I reckon this is going to be hard to find for under $100 without shipping. The carded Kubs cost about $30 delivered for the collectors club and are going for around $50-75 now. The odd one a bit lower than that.
The Max Rebo set is going to cost around $75 delivered from the collectors club. I think therefore, most people won't sell them for under $100. So I think $100-110 plus shipping is what they will come down to. But I think $29 sounds a bit high for shipping. I'll be getting a couple in this week so I'll check it out.
As for the lottery date, I don't remeber the exact date, but I think it's April sometime. I think Leia and the Droids Fett had about the a 2 month timeframe between batches.
