I think the 40% off BB-8 is probably the best deal here in the USA. Almost everything else on sale is meh.
I finally saw the UCS ISD in person. The videos don't do it justice. It looks awesome... until you see the price.
Also got to see the new Yoda in person. It finally hit me why his eyes and face look funny. His head is about 10-20% too small compared to his body. The length of each of his ears should be around 60% the width of Yoda's head and extend beyond his shoulders and arms. On the new LEGO set the body, light saber, hands, and feet all look great. But his entire head is a miss. I don't know if they needed to save pieces to get a $100 price tag or what, but his head needs to be 6-8 bricks wider (3-4 each side) and the ears re-proportioned. Compare this pic from Revenge of the Sith, which is the look I think they were going for, to the LEGO pic and I think you'll see my point.
Edit: Found a better pic of Yoda's full body w/lightsaber
