A deal on grocery delivery from Apple and Instacart, a big win for TSMC, and it's been an interesting week for Spotify:

• Pay for your grocery delivery via Instacart with Apple Pay, and Apple will pick up the delivery charges through January 10th
• TSMC will reportedly build all of the A12 processors for this year's iPhones, edging out Samsung on what could be a huge order
• Spotify has announced that it has 70 million paid subscribers, is filing for an IPO to go public, and might have to pay out $1.6 billion in a lawsuit
