Monday morning strategy watch: Amazon Prime

News today that Amazon is tweaking its ‘Prime’ offering.

Starting today, Amazon is rewarding its Prime users by offering free music store credit in exchange for longer shipping times.

At the check-out, Prime member just have to select “FREE No-Rush Shipping.” That give Amazon a full 5-7 days to get your purchases to you. Which seems, like, forever. But, when the items ship you get a $1 credit to spend on music at the Amazon MP3 Store. The credit has to be used up by January 31 2012.
