As one of its daily deals, Amazon Local offers a $3 Amazon MP3 credit good towards any MP3 album or song with no minimum purchase required for free. (You'll receive a coupon code that can be applied at the Amazon MP3 Store directly.) That's the largest MP3 credit offer, with no minimum purchase required, we've seen from Amazon. (We saw a free $4 credit good towards albums of $8 or more three weeks ago, since expired. We've also seen free $1 and $2 credits with no minimum purchase required.) The credit must be used by July 12. Deal ends today.

Update: This deal is now active again.
