Thanks to the individual who warned about the impossibility of returning my 'free sample' of RezV. Because she warned that they charge (my) credit card two weeks after they send the item--NOT two weeks after you receive it, I was able to reach my credit card company and stop the charge before it was credited to my account. I emailed the company three times asking for instructions on returning the sample; had they responded I would have been able to return it on time. There are no instructions at their site to tell you how to return the sample. I appreciate the availability of such valuable information. read full review »
