Target has a general 20% off sale going on right now for most Star Wars Legos. They've also got a buy $50 and get a $10 gift card that applies to Legos, including advent calendars. And you can add your 5% Red Card discount with free shipping.
I've placed three different orders this morning to keep cashing in on the gift cards. Ultimately its allowed me to hit between 30-40% discount, which is pretty good for Legos.
