Fuji A170 (AA-based P&S) ships for $80 (A220 for $90)

You don't have to break the bank to get a basic AA-based P&S digital camera! For just $80, with free shipping, you can get the sold and shipped by Amazon.com itself, along with third-party sellers.

This camera uses AA batteries and SD/SDHC memory cards, making it the most affordable in terms of maintainability for those who do not object to rechargeable AA batteries.

But unlike five years ago where you couldn't even get a fixed-lens camera at this price, this one has a 3x zoom lens, 2.7" display, and a 10mp sensor, and yes, of course face detection. But no sensor/optical stabilization. It's not a free lunch at $80 :)

The camera was announced in mid-July 2009, along with the 12-megapixel A220 which goes for $89 with free shipping.

And one more thing on these two, you also get a coupon code for 55 free prints from Shutterfly. The 55 prints are broken down as follows:
+ one 8x10
+ four 5x7
+ fifty 4x6
