According to the search results, replacement in Flipkart refers to the process of replacing a product with an identical one in case it is damaged, broken, spoiled, or defective. Flipkart offers a replacement guarantee for all returns, and customers can opt for a replacement or refund depending on the category of the product ordered. If a customer is unsatisfied with the replacement or if the specific product or model that they want is out of stock, they can opt for a refund. The number of replacements allowed may vary depending on the policy applicable to the product. To initiate a replacement, customers can click on the Orders tab in the Flipkart mobile app or desktop site and follow the next steps of the process. The Flipkart product returns team will take over from there.
