The regular retail price is $99.99. TRU typically overcharges on Lego. If you are near a Lego store they have peel off discount cards this weekend only with a minimum (and most common) discount of 10%. That would make the set $90 plus tax plus you also would get a free pick a brick box to use after the holidays and fill it up from their pick a brick wall. If you purchase $9 more in store there is a special holiday set you get for free with a $99 purchase.
But, a nice deal if you do not want to brave the mall today or are not near a Lego store.
