Best Buy has a "Low price Guarantee" policy on many items that you can check on their web site and above the price they will show if that policy is in place for that item. Amazon is one of the many they have listed that they will match. I recommend you read it for yourself as it seems some people here just spout off information with absolutely no idea if that info is up to date or not. As for the product you are asking about you will have to check your store as they no longer have this item on their website. You should also read their "upgrade and save" policy as it does state that markdowns are taken from original or promotional price so you will have to try and see. ymmv.
also keep in mind that best buy will check to make sure the competitor shows or has the item in stock.
Damn...sale on the complete SW set might have caused me to buy. But I still want the non-mollested versions of 4-6, so I'll keep hoping some day Disney will come through where Lucas didn't (assuming they settle the whole Fox deal).
