2 Day Sale at Toys R Us
Valid Tuesday 11/22 thru Wednesday 11/23, Toys R Us is running yet another Buy One, Get One 50% Off promotion. This sale, however, excludes Star Wars and apparently only applies to "Regular-Priced LEGO construction sets." I'm sure we could argue with TRU what constitutes a "regular" price, but I digress.
Update: As expected, "Discounted" sets were indeed included in the sale when it launched though TRU will likely fix that.
Update 2: Brickset Forum member sidersdd has provided coupon code "TONSOFFUN" to get $15 off $100+ orders.
