# FAQ
## How to set the flash sale amount?
The amount of the flash sale is the amount set in the product management. The flash sale essentially only sets 4 elements:
1. Whether flash sales are enabled for this product;
2. When does the flash sale start;
3. When will the flash sale end?
4. How much is the inventory?
The time has not started, the time has ended, and the inventory is 0 (sold out), the product cannot be ordered. So there is no need to set the flash sale price separately
