Bundles and Quantity Breaks for Supplement Brands: Pricing and Discounts

How to price supplement bundles and quantity breaks: tier structures, discount depth by margin, presentation, FTC price rules and subscriptions.

Article summary

TL;DR

Price supplement bundles in months of supply (1, 3 and 6 months), with the per-month price falling as the supply grows and the 3-month tier highlighted. Keep standing discounts around 10 to 25%, check the contribution per order of each tier, and only show a "was" price you actually charged for a real period of time.

Eightx reports AOV lifts of 15 to 25% for 2-bottle offers and 25 to 40% for 3-bottle offers in supplements (sources not disclosed).
Eightx advises standing discounts of 10 to 25% and never stacking subscription, bundle and sitewide discounts on one order.
A "was" price must be "the actual, bona fide price" offered "for a reasonably substantial period of time" (FTC, 16 CFR 233.1).
"Buy one, get one free" offers must state all their conditions up front (16 CFR 233.4).
A bundle on subscription keeps the higher order value and adds recurring revenue.

The 4 bundle structures

Structure	Example	Best for	Watch for
Supply tiers	1 month / 3 months / 6 months	A single hero product	Margin on the 6-month tier
Quantity breaks	2 bottles 10% off, 3 bottles 20% off	Products bought in multiples	Shoppers comparing per-unit prices
Buy X get Y	Buy 2, get 1 free	Clear, simple promotions	FTC rules on "free" offers3
Stack or kit	Two complementary products together	Introducing a second product	Inventory and kitting

Supply tiers
1 month / 3 months / 6 months. For a single hero product.
Quantity breaks
2 bottles 10% off, 3 bottles 20% off. For products bought in multiples.
Buy X get Y
Buy 2, get 1 free. Clear, but FTC rules on "free" offers apply.
Stack or kit
Two complementary products together, to introduce a second product.

Supply tiers suit supplements best: the customer thinks in months of use, not in bottles.

How deep should each tier go?

A deeper discount lowers your margin rate. It can still raise your contribution per order, up to a point.

Illustrative figures: a bottle sells for $40, costs $8 to make, and shipping costs you $6 for one bottle, $7 for three, $9 for six.

Tier	Discount	Price	Product cost	Shipping	Contribution	Contribution per bottle
1 month	0%	$40	$8	$6	$26	$26.00
3 months	15%	$102	$24	$7	$71	$23.67
3 months	25%	$90	$24	$7	$59	$19.67
6 months	25%	$180	$48	$9	$123	$20.50
6 months	35%	$156	$48	$9	$99	$16.50

3 months at 15% keeps the most per bottle of any bundle.

Illustrative example. Figures from the table above.

What the table shows:

Every bundle beats one bottle on contribution per order.
Each extra 10 points of discount costs you $12 per 3-month order and $24 per 6-month order in this example.
The 6-month tier at 35% earns less per bottle than the 3-month tier at 25%. Push the middle tier.

Eightx recommends standing discounts of 10 to 25%, with deeper ones kept for launches or clearly different tiers1.

Present the tiers so the choice is easy

Three tiers, not five. More options slow the decision.
Highlight the middle tier as "Most popular" or "Best value", if it is true.
Show the price per month under each tier, and the savings in dollars.
Keep tier 1 at full price, so the others have a clear baseline. App guides recommend the same4.
Show shipping on each tier, especially if larger tiers ship free.
Repeat the tiers at the bottom of a long product page.

Example

"1 month: $40" / "3 months: $102, $34 a month, save $18" / "6 months: $180, $30 a month, save $60, free shipping".

Price claims the FTC cares about

Bundle pages are full of price comparisons. Two FTC guides apply directly.

Claim	Rule	Source
"Was $60, now $40"	The former price must be "the actual, bona fide price" offered to the public "for a reasonably substantial period of time"	16 CFR 233.12
Fictitious "compare at" prices	If the former price is not genuine, the bargain is "a false one"	16 CFR 233.12
"Buy 2, get 1 free"	Not free if you raise the regular price, cut quantity or quality, or add hidden conditions; state all terms up front	16 CFR 233.43

"Was $60, now $40"The former price must be a real price offered for a reasonably substantial period (16 CFR 233.1).Use your real regular price.
A "compare at" price you never chargedThe bargain is "a false one" (16 CFR 233.1).Show the savings against tier 1.
"Buy 2, get 1 free"Not free with a raised regular price or hidden conditions (16 CFR 233.4).State all terms up front.

Watch out

A "compare at" price you never charged is the easiest price claim to get wrong. Use your real regular price, or show the savings against tier 1.

Bundles and subscriptions

A subscription on a single bottle discounts a small order. A subscription on a bundle keeps the order large.

Offer	Order value	Next order	Discounts
1 bottle on subscription	Lower	30 days	Subscription discount
3-month bundle, one-time	Higher	Customer decides	Bundle discount
3-month bundle on subscription	Higher	90 days	One discount only

A bundle on subscription keeps the order large.

From the table above.

Pick one discount per order. Eightx advises against stacking subscription, bundle and sitewide discounts1.
State the renewal terms before the card is entered, and get express consent, as ROSCA requires5.

Setup: subscription billing for supplement brands.

Operations: what bundles change behind the scenes

Inventory: keep bundles linked to the single-bottle SKU, so stock stays accurate.
Shipping: heavier parcels may change your shipping tier. Price it into each tier.
Expiry dates: a 6-month supply needs stock with enough shelf life left.
Refunds: decide whether unopened bottles in a bundle are refundable, and say so on the page.

Test the tiers

Start with 1, 3 and 6 months at 0%, 15% and 25%.
Change one variable at a time: discount depth, highlighted tier or free shipping threshold.
Measure contribution per visitor, not only AOV or conversion.
Wait for the reorder window before judging the 6-month tier.

Judge each version on contribution per visitor.

How to run the test: checkout A/B testing for supplement brands.

Frequently asked questions

How much discount should I give for buying 3 bottles of a supplement?

Around 10 to 20% is a common starting point; Eightx advises keeping standing discounts within 10 to 25%. Check contribution per order for each tier: a deeper discount can still beat a single bottle, but it may earn less than a lighter one.

Is "buy 2, get 1 free" better than a percentage off?

It is simpler to understand, and it equals about 33% off the three bottles. Under FTC rules, it must not come with a raised regular price or hidden conditions, and all terms must be stated up front. A percentage on supply tiers is usually easier to control for margin.

Should supplement bundles be sold on subscription?

They often should. A 3-month bundle every 90 days keeps a high order value and adds recurring revenue. Use only one discount on that order, and show the renewal terms clearly before payment.

Can I show a "compare at" price on my bundles?

Only if it is a real price you charged the public on a regular basis, for a reasonably substantial period of time (16 CFR 233.1). Otherwise, show the savings against your single-bottle price instead.
