Delivery, drops and refills
What is the difference between “non-drop” and “refill guaranteed”?
Last updated by The PanelCompare editorial team
Which words are claims and which are mechanisms?
| Term | What it is | Can you act on it? |
|---|---|---|
| Non-drop | A prediction about durability | No |
| High retention (HR) | A prediction about durability | No |
| HQ / real / organic | A description of the source accounts | No |
| Refill, with a window | A contractual remedy with a mechanism | Yes — a button, or action=refill |
| Auto-refill | The same remedy, applied without you asking | Yes, automatically |
| Cancel | Buyer-initiated cancellation, generally pre-start only | Yes, if the row advertises it |

How should you read a row that says both?
Ignore the adjective and look for the flag. The catalogue exposes refill and cancel as per-service booleans, so “non-drop” in a row name with refill set to false is a row with no remedy at all. Where both appear, the refill window is the part that means something, and its length is the part worth comparing between panels.
The two words are priced differently, which settles it
A supplier charges nothing extra to call a service non-drop and charges +20% to +250% to attach a refill window to it. The market has already told you which of the two it considers a liability.
Think this answer is wrong?
Prices, refill terms and platform policies in this market all move, so an answer that was right in September may not be right in December. Every figure above names its source and the date it was checked; if one of them is stale or wrong, the correction process on the about page has a two-working-day reply target, and corrections are published with a dated note rather than quietly patched.
