Vostrotone via Amazon offers Prime members this Bluetooth Keyboard for iPad for $17.39 with free shipping. (Non-members can get free shipping on orders of $25 or more; otherwise, shipping adds $8.48.) That's a buck under our mention of a similar keyboard from two weeks ago and the least expensive full-size Bluetooth keyboard we've seen for iPad. (It's a current price low for such a keyboard by $3.) It also works with desktop and laptop computers and features 78 low-profile keys, 1-touch access to Spotlight, home screen, and more. Two AAA batteries are required (not included).

Amazon Prime membership is $79 per year; however, Prime is free for college students for six months, and free for parents and caregivers for three months.
