No, I cannot refund items separately.

1. When purchasing items with discounts, merchants often evenly distribute the discount amount to each item, so if you return an item separately, there is no guarantee that the item still meets the discount requirements.

2. In addition, when purchasing items with discounts, there are often promotional rules, such as how many items must be purchased to enjoy the discount. If you refund separately, you may violate the promotional rules and cause the discount amount received to be deducted.

3. If you really need a refund, you can consult the merchant and follow its return policy.
