Shame on you Spotify! You promote free Google Mini for Subscribers. Only to find out you MUST share credit card information to get a FREE (repeat FREE) gift. In a world where data privacy is a MUST and Data theft is rampant, you FAIL Spotify. You should at least specify this in the free email offer rather than let it go all the way to checkout time. Im sure you will fault Google for this . But you should know the business arrangement and be transparent with your subscribers about it ahead of time.
