Went looking for batteries for my new spark. Target has them on clearance for $24.98. I was able to price match between Targets. Use a red card and in theory save another 10%. They show full price online, but ring up at the clearance price in store.

The DJI Mavic Intelligent Flight Battery (8138068) is $45 (50%) in some stores as well. Thanks to Formless for the mavic info
