I ordered the 30 day free trial. Their information states that if product is not returned to them within 30 days of product "shipping date", you will be charged for the product. Plus they put you on a membership program where they will automatically ship to you every 30 days, unless you stop it. Their shipping date was August 11th, I received it on August 14th, and they charged my credit card on August 28th, only 17 days after their shipping date. I have tried to call them, but they don't answer the phone. I have sent them two e-mails, so we will see what they do about it, but they should not have charged my credit card so quickly, as I didn't even have time to return the product before the charge. I would not recommend that anyone bother with their so-called free trial.
UPDATE: I just received notice that Superfoods Rx has cancelled the auto ship membership as I requested. However, at the bottom of their e-mail it said "Additional charges may apply". I am not sure what this is in reference to, as I already paid for the product and shipping. But if there are any other charges from this company I will repost an update.
