The 3-bottle pack sits in the middle: $69 a bottle, $207 in total, free shipping.
It covers a stated 90-day supply, which works out to about $2.30 a day by our arithmetic. The page lists two digital guides with this pack, out of three bonus guides in total. Which two is not specified.
It also lines up with the lower end of the 90 to 180 day timeline the brand suggests.
The guarantee still ends at day 60, so you cannot judge a full 90 days before the refund window closes. Whether it makes sense depends on your confidence and your plan for tracking results. Confirm the price and the bonuses at checkout.
