Flash Sale Extension for Flipkart & Amazon India

A flash sale extension is a Chrome browser tool designed to help you purchase products during limited-time sales before stock runs out. Flash sales on Flipkart and Amazon often sell out within seconds due to high demand and limited inventory. ChromeXT automates the add-to-cart process, clicking the buy button the instant the sale goes live - much faster than humanly possible. This gives you a significant edge when competing for high-demand products like new smartphones, gaming consoles, or limited edition items.

Getting started with ChromeXT takes less than 2 minutes:

1. Install ChromeXT from the Chrome Web Store and pin it to your toolbar for quick access.
2. Navigate to the product page on Flipkart or Amazon where the flash sale will happen.
3. Open ChromeXT and configure the sale time. You can manually start the script or let it run automatically.
4. Wait for the sale - ChromeXT will automatically add the product to your cart the moment stock becomes available.
5. Complete payment quickly. On Flipkart, enable auto-checkout with Cash on Delivery for even faster checkout.

Pro tip: Keep your payment details saved and stay logged in for the fastest checkout experience.

Yes, ChromeXT is completely free with no hidden charges, subscription fees, or premium tiers. Every feature is available to all users at no cost. We sustain the extension through affiliate partnerships with e-commerce platforms - when you make a purchase, we may earn a small commission at no extra cost to you. This runs silently in the background and doesn't affect your shopping experience, prices, or checkout process in any way.

ChromeXT is designed with your security as the top priority. Here's what you should know:

• No data collection - We don't collect, store, or transmit your personal information, browsing history, or shopping habits.
• No password access - ChromeXT never asks for or stores your login credentials. You log in directly on Flipkart/Amazon.
• Secure payments - All payments happen directly on the official e-commerce websites. We never handle your payment information.
• Transparent operation - The extension only automates the add-to-cart button click. Nothing more.

ChromeXT's instant add-to-cart feature gives you the best chance of securing these high-demand devices at launch prices.
