29-10-2011· So no, I don't believe Green Polka Dot Box is a scam. I'm a consumer, just like you. I have a Rewards membership, and I've referred a few people to GPBD. I have talked to Rod, but I don't have any special insider knowledge. But from what I see, no, GPDB isn't a scam. Is it fail-proof? No, of course not - no business is.
