Best Buy is knocking $75 off any iPhone 5s when you agree to sign a new 2 yr contract. Just to clarify, this includes all carriers, colors, and capacities. This is one of the only deals we have seen on the 32GB/64GB models since they were introduced this fall. Act quick, Some popular models (16GB, gold, etc) are already selling out online but are available for in-store pickup. As a pricing comparison, AT&T ran a promo in November offering the 16GB model for $100, but did not discount any other capacities or carriers (obviously!). The iPhone 5c is also available for $50.
The iPhone 5s features Touch ID security, an A7 chip with 64-bit architecture, and an improved iSight camera with slow-mo/burst mode capabilities.
