Canon batteries for the SX260 are $59.99
An on-line site, eBatts.com, offers for $14.95(no shipping charge)
Are thet legit?
Not sure about the "eBatts.com", haven't tried them.
But, I use Wasabi batteries from Bluenook in all my cameras and have never had a reason to complain. Good prices too. Sometimes they have online coupon codes you can use at check out, you can find by google search.
