It's not a massive discount, but if you're upgrading you could do a lot worse.
Best Buy has launched a new program that hopes to drive a bit more consumer interest in Blu-ray discs. It's called "Upgrade and Save" and it aims to give you a way to upgrade from DVD to Blu-ray while still getting a little value out of your old DVDs. Trading in a DVD will get you a $5 coupon, usable on any Blu-ray movie over $9.
As nice as it would be if these were just straight-up gift certificates, these are coupons, which means you can only use one $5 coupon per Blu-ray. You're also limited to getting five of these coupons per visit, so if you have a big collection you want to turn in you might want to bring a few friends to help.
