You push a bit hard [ as does everybody] to purchase in multiples. I’m old and I want to see if something really works before I get a lifetime supply. If I like it I will be back to purchase more. As I did. Perhaps you should think about that and let people try you product with less multiple offers at first. The constant push to purchase quantity’s of an unknown product seems to me to admit that it does not work and your ad man knows that. Let the product sell itself.
