i was able to find a $40 off $199 coupon through google in november and got my daxter psp then. it's extremely YMMV if it works (i was lucky enough), especially since you'll be printing it out. it's also iffy if they'll let the fact that you're purchasing a hardware BUNDLE slide.
i recommend trying to get a "moving pack" at the post office (change of address packets) in hopes of an official coupon - some people found circuit city coupons there, but in my area they give out 10% off limited best buy items.
anyways, good luck with that! that coupon sure helped justify my purchase even more, especially as a cag...
