So I signed up for 3 months from July- Sept and paid $96.30 coz I used the promo code REFER5 at that time. I extended it for another 3 months so of course it automatically renews it for me. I am looking at my billing info and wondering why they are charging me $37.45 for the Oct month. Don't they usually charge for the whole 3 boxes at one time which comes up to $101.65 (for me - $95+$6.65 tax =$101.65).? If they charge me $37.45 per month that would come up to $112.35. That's another $10 right there. Can anybody shed some light? This month is already processing. Thanks.
