The Cottage is my favorite, too. And my first set ever. If I see it 20% off again in January, I'll pick up a few more.
Story: seeing the cottage on sale was my eye-opener to the potential of Lego. The clerk told me an eariler customer bought 11 @ 20% off. That made so much sense I couldn't bear it. I probably found BrickPicker that same night.
Anyway I think I'm done buying this year. I've got about 100 sealed sets of varying sizes, and no more than 7 of any one set. I have 7 HDs, 3 VCs, 5 UGs, 4 R2s, 4 VWs, 4 HHs, 3 41999s, 3 8110s, B-wings and Funhouses and and a Super Star Destroyer, oh my.
I don't know if I really expect any of them to eol this year. Anyway that's my keeper stash for now. Although I do still want a Kingdoms Joust, so maybe one more buy before 2014.
