All-in monthly cost

The medication price is turned into a month first: a price billed every four weeks is charged thirteen times a year, not twelve, and a quarterly or yearly price is spread over its months.

Each fee is then added the way our reviews add it. A monthly fee and a per-order shipping charge land in every month. A one-time consult lands in the first month only. An annual membership is paid in full in the first month and counted as a twelfth in each month after.

The first year adds each fee as often as it is actually charged in a year, which is why it is not simply twelve times the second month.

The seller list opens on the receipts of the 12 sellers we have reviewed. A fee a seller does not state loads empty and is named under the bill; it is never counted as zero on the seller's behalf.
