How Many Bottles Do You Actually Need? The Case for a Five-Bottle Routine
One 60-capsule bottle covers about 15 days at the label's serving, so most routines start at five. Here is the real math…
From five eligible items, our August 2026 promotion adds a free Lady Blossom Serum automatically, no code needed. Here is exactly how the gift tiers work.
This August, orders of five or more eligible items unlock 25% off and a free Stherb Lady Blossom Serum ($15 value) automatically — no code needed. Free shipping starts at the same five-item tier, since a five-bottle order already clears both shipping thresholds. At eight items, the gift upgrades to a Stherb Nano Breast Serum 15 ml ($50 value) in place of the smaller gift.
If you have been thinking about stocking up on PM Capsules, this is a good month to actually do it. Alongside our usual discount ladder, we are running a gift with purchase for August 2026, and we wanted to walk through exactly how it works, what is included, and how it lines up with our normal shipping rules.
Nothing about checkout gets more complicated. There is no code to remember and nothing to add to your cart separately — the discount and any gift are applied automatically once your order reaches a qualifying quantity.
The ladder counts eligible items in your cart in any combination — we are using bottles of PM Capsules below since that is the most common way people reach it. This campaign runs 1 to 31 August 2026.

Maximum stock-up tier. The bigger gift replaces the Lady Blossom Serum rather than adding to it.
Two eligible items already take 10% off; three to four take 15%. The free gift specifically starts at five.
To put the numbers plainly: eight bottles at our regular $45 price would normally run $360. With the discount, it comes to $270, shipped free, with a $50 serum included at no extra cost. That same free shipping already applies from the five-bottle tier too, since $225 clears both the $100 standard-shipping and $200 DHL Express thresholds.
The Lady Blossom Serum is one of our feminine-care serums, formulated with Pueraria Mirifica and botanical extracts. On its own, it retails for $15. From five eligible items in your cart, one is added to your order automatically at no charge, packed in the same shipment as your capsules.
We made a deliberate choice to reserve the Nano Breast Serum specifically for the eight-item tier. At $45 a bottle, adding a $50 gift to a smaller order would push the combined value of discount and gift well past what we consider a sustainable ceiling. Keeping it at the eight-item level keeps the whole offer balanced. It replaces the Lady Blossom Serum rather than stacking with it — every qualifying order gets one gift, and the higher tier simply sends the more valuable one.
| Bottles | Regular Price | With 25% Off | Shipping | Gift |
|---|---|---|---|---|
| 5 | $225.00 | $168.75 | Free | Lady Blossom Serum ($15 value) |
| 6 | $270.00 | $202.50 | Free | Lady Blossom Serum ($15 value) |
| 7 | $315.00 | $236.25 | Free | Lady Blossom Serum ($15 value) |
| 8 | $360.00 | $270.00 | Free | Nano Breast Serum 15 ml ($50 value) |
Every row above clears both free-shipping thresholds — $100 for Standard Shipping and $200 for DHL Express — so shipping is free from five bottles up. Full shipping details are on our worldwide shipping page. Prices shown are for August 2026.
The idea behind this offer is helping you walk away with a complete routine, not just a lower number at checkout. A 25% discount is meaningful on its own, but pairing it with a serum you can actually use alongside your capsules is what we were going for.
No. Both the tier discount and the gift are applied automatically once your cart qualifies. There is nothing to enter at checkout.
Yes, the gift is added to your cart automatically as soon as your order reaches the qualifying quantity, the same way the discount is. If a gift item were ever out of stock, it simply would not be added, but this is checked at checkout in real time rather than promised in advance.
Only one promotion applies per order. If you also try to use a coupon code, our system removes the smaller of the two and keeps whichever benefits you more.
Not this month. The Lady Blossom Serum is tied to the five-to-seven item tiers, and the Nano Breast Serum is reserved for the eight-item tier, so the gifts are not interchangeable between tiers.
No. Your gift is added as a line item in the same cart and ships together with your order in one shipment.
Mainly value and tier. The Lady Blossom Serum is a $15 product and unlocks from five eligible items; the Nano Breast Serum 15 ml is a $50 product and replaces it once your order reaches eight eligible items.
Yes. Two eligible items already unlock 10% off, and three to four unlock 15% off. The free gift specifically starts at the five-item tier.
Yes. The discount ladder and gift tiers work the same way regardless of which country you are ordering from, as long as your cart quantity qualifies. Shipping cost and timing still depend on your destination.
Everything is applied automatically, and available while supplies last this month.
