Fluz is a new cashback app. Most recently they offered 2.5% back at ODOM for a short period of time. I missed out on this beta test and see no offers now but after contacting them on Facebook they'll be rolling out in the next few weeks.
This is the first cashback app I've seen that has the MLM style cashback where you receive cashback when your down line does. There doesn't seem to be any posted stats about how the MLM cashback works at this time.
Fluz runs on the Empyr backend. I didn't have any issues adding cards but can't say if purchases stack with other Empyr apps.
