What are opinions on Acai Berry?

yes, if ordered online, they will scam you. they say its just a small amount to purchase it online, but once you order it they'll bill you probably 30 times more the amount you paid... maybe even more. so if you dont want your credit card billed to an outrageous extent, my suggestion to you is to watch what you buy when checking out acai products sold on the internet.
The health claims are at the very least quite exaggerated.
