Your first order is a learning exercise. Your reorders are a logistics problem — and the regulars who structure them well spend less per milligram and run out less often. Here is how the structure works.
The free-shipping threshold is a planning tool, not an accident
U.S. orders over $90 ship free. The difference between “I added a pack and happened to cross $90” and “I planned the order to cross $90” is a shipping fee, every order, forever. The habit: look at your subtotal before checkout, and if you are within reach of the threshold, add the pack you will actually use next — not a random fourth flavor. The free shipping post covers the rule, and the cost per mg guide covers the per-mg math behind the pack choice.
Build a two-to-three pack rotation, not a one-pack habit
Most regulars settle on a rotation of two or three flavors and reorder in that pattern. Two reasons: variety keeps the experience from going flat, and a pattern makes reorders mechanical instead of decisions every time. The stocking-up guide is the full write-up on building a rotation, and the flavor roundup is the reference for picking the rotation members.
When the big pack wins
Once your routine is stable — same strength, same schedule, known per-mg consumption — the large packs (the 300mg 30-count, 750mg, 1000mg) are where the per-mg value lives. The price guide has the numbers, and the rule of thumb: stable routine = big pack; exploring = small packs.
The inventory discipline
Know your consumption rate (tablets per week, honestly), and reorder when you are at roughly two weeks of supply, not zero. Two reasons: it removes the “out on a Friday” problem against the 1–2 business day processing window (shipping policy), and it keeps you from panic-buying the wrong format in a hurry. Storage is the other half of the discipline — sealed, cool, dark, dry, per the storage guide — because a pack that sits three months on a counter is not the pack the label describes.
Account shortcuts
If you create an account (optional, at My Account), order history and reorder shortcuts make the mechanical part one click. Questions on any of it go to the FAQ or the contact page.
