The arithmetic
Gluco6 cost per day, and which pack to choose
Gluco6 cost per capsule and per day
| Pack | Per bottle | Total | Shipping | A day |
| 2 bottles | $69 | $138 | $9.95 US shipping | $2.30 |
| 3 bottles | $49 | $147 | Free US shipping | $1.63 |
| 6 bottles | $39 | $234 | Free US shipping | $1.30 |
US shipping is $9.95 on the two-bottle order and free on the three- and six-bottle orders. International orders add $19.95 on every pack.
A bottle holds 30 capsules and the direction is one in the morning, so the daily figure for any pack is its bottle price divided by thirty. That is the last column above, and it counts the capsules on their own.
Postage moves one of the three. Two bottles is the only order that adds US shipping, so $147.95 leaves the card rather than $138, and 60 days of capsules works out at $2.47 a day. Three bottles is $1.63 a day and six bottles is $1.30, both posted free inside the United States. The smallest order is the most expensive way to try Gluco6, and it is the only one the fee falls on.
Now set the two smallest orders beside each other at the checkout. Two bottles with its postage is $147.95. Three bottles, posted free, is $147. The larger order is $0.95 cheaper to pay for on the day and carries another 30 capsules with it — the one piece of arithmetic on this ladder that nobody does in their head, and the reason the smallest pack is rarely the cheapest decision.
Read across the whole ladder and the same 60 days of capsules costs $147.95 bought as two bottles, $98 bought as three and $78 bought as six. Six bottles asks $234 on the day, so the lowest daily figure here is bought with the largest single payment. An international order adds $19.95 whichever pack it is, which the shipping page sets out in full.
None of these figures is a charge that repeats. Payment is taken once at the checkout, nothing ships automatically afterwards, and the checkout shows the live total before any card details are asked for.
