Enter your details and select the flavour you would like and Eat Natural will send you out a free bar! Can't say fairer than that. The flavours on offer are peanut & popcorn (strangely) and coffee and chocolate. Once you've ordered they'll send you one out within 7 days.

Only one per household. It's not the one pictured by the way, that was just the first Eat Natural image I found on the net.

Never tried Eat Natural bars before I don't think so I can't tell you what they're like, but hey, it's free :)
