Compare two sellers
Two sellers on different billing cycles cannot be compared on their advertised prices at all. Restate both as a calendar month and the order sometimes reverses.
First seller
Second seller
Head to head
Enter what each seller bills and how often. Both charges are restated as a calendar month before anything is compared.
Why the smaller number is not always the cheaper one
$299 every four weeks against $310 a month: the first looks eleven dollars cheaper and is fifteen dollars a month more expensive, because it lands thirteen times a year and the other lands twelve. Over twelve months that is $180 pointing the opposite way to the sticker. This is the single most common way a price comparison goes wrong, and it needs no bad faith from anyone to happen.
The same reversal shows up between a prepaid bundle and a month-to-month rate. Those are also two different products — a bundle usually has to be paid up front and is often non-refundable — so a cheaper monthly cost from a bundle is not straightforwardly the better deal. The tool tells you the arithmetic, not which risk to take.
What is not in this comparison
Shipping, consultation and membership fees, what happens to the price when your dose changes, whether supplies are included, and which states a seller ships to are all outside it. Every one of those is on the price index row for the seller, and the ones that move with the dose belong in the course calculator.
