Just checked this out at 1:04 am MST.
The 30% off sale appears to be only on "top selling" Star Wars items. However, the site seems to contradict itself because in another place it says "all Star Wars" on sale. The only new sets that showed up when I clicked the 30% off banner were the Y-Wing (9495) and Geonosian Cannon (9491), but when I add those to my cart, they don't show up with the 30% discount.
Maybe I'm just too early and the website is not fully updated yet.
On the Series 6 minifigs "buy 2 for $5.00" sale, it appears to literally mean "buy 2 - no more, no less - for $5." I tried to put 20 in my cart, 2 of them went in the cart for $5, and 18 of them went in the cart at full price.
