# Adding NFTs to a Sale

**`add_nfts_to_sale<CURRENCY>(...)`**\
**Purpose**: Add more NFTs to an existing sale before they’re sold out.

**Key Parameters**:

* `sale`: A mutable reference to the `NFTSale` object.
* `nfts`: Additional NFTs to add.
* `asset_ids`: The IDs of the NFTs being added.
* `collection_cap`: For authorization checks.
* `sender_balances`: User balance objects to ensure the user adding NFTs has them available.
* `ctx`: The transaction context.

**Process**:

1. Verify the caller is the sale’s creator.
2. Check that the sale is still active.
3. Move additional NFTs into the sale’s asset\_ids list.
4. Update `nft_count` and emit listing events.

**Use Cases**:

* A creator initially lists 50 NFTs but later decides to add another 20 NFTs after seeing strong demand.
* A seller wants to restock a sale as the initial batch sells quickly.
