^ I've waited all day for that and nothing... Though really for me the only difference is the shipping cost (free at Amazon vs $3.49 at GS). I'd rather use up my GS credit anyway since I can use my Amazon credit on any number of other things. So even if Amazon does match at the end of the day, I'd probably prefer the GS option at +$3.49 anyway. Amazon had their chance to get my business for 2/3 of today and didn't pull the trigger.
Tempting! Possible BB will have it on DOTD for $10
Blah - I'll probably regret this when the above thing happens, but I went ahead and ordered it for shipping: $23.48. That saves me the time (and gas) of running out today to get it so it was definitely worth paying that vs $19.99 in store. However, if it is $10 any time within the next 6 months I'll regret this for sure.
Maybe this will force me to play it as soon as I get it instead of putting it on my big pile o' Move and Kinect games
