If you do decide to hit one of the stores, also note that there's a promo for a free Max minifigure key chain with purchases over $35 dollars. In store you will need the coupon found in the most recent, free LEGO Club magazine. Call to confirm your store has these in stock before heading out.
You can also take advantage of this offer at LEGO Shop at Home online with coupon code MX09 (US) or MXCA (Canada).
