## Short answer
Discount codes are automatically applied at checkout. Some codes exclude subscriptions, bundles, or returning customers.
## Steps
- Review code **conditions** (expiry, minimum spend, first‑order only).
## If/Then
- **If it doesn’t apply to a subscription** → many codes are **one‑time only**.
- **If stacking doesn’t work** → most codes **cannot be combined**.
- **If currency differs** → the final amount updates at payment based on your currency.
## What we need from you
- The special discount offer you tried, a screenshot of the cart/checkout, and the country/currency set
## Notes
- Some promotions are market‑specific (by language/country).
