Value Buy Battery via eBay offers this Rotating Smart Cover for iPad mini in Blue for $5.75 with free shipping. That's the lowest total price we could find by $8, although we saw a similar case for $2 less in February. It includes a stylus, screen protector, and microfiber cloth.

The case is also available for iPads 2/3/4, iPad Air, or iPad mini Retina for $6.95 with free shipping.
