Since Best Buy beefs up the prices of ordering online with an Order Charge and Tax I'm trying to figure if their $10 digital Coupons you get when you preorder titles like Black Hawk Down, is worth it. They have a prerelease price of $19.99 on it. Now that'll probably be a title they sell for $17.99 or less. If they drop the price do you get then new price when it ships plus the digital coupon? I took advantage of this on Harry Potter before they dropped it, but that was before I realized all the Hidden charges.
