As one of its daily deals, Yugster offers the factory-refurbished Belkin Grip Power 2,000mAh Battery Case for iPhone 5/5s in Blue or Purple for $24.97. Coupon code "FreeYugBuck" cuts it to $23.97. With $5 for shipping, that's a buck under our refurb August mention and the lowest total price we've seen. (It's also $21 below the best price we could find for a new model.) It features a shock-resistant bumper, anti-glare camera ring, microUSB charging cable, and headphone adapter. A 90-day Belkin warranty applies. Deal ends October 18 at 6 am ET.
