Delivery Availability Checker

Help you find the Amazon, Costco and Instacart delivery windows

The Delivery Availability Checker is a versatile Chrome extension designed to help users monitor delivery windows across multiple platforms including Amazon Prime Now (US, UK, Italy), Amazon Smile, Amazon Fresh, Whole Foods, Costco (same day delivery), and Instacart. By automating the refresh of the shipping schedule page, it replaces the cumbersome process of manual refreshing to spot available delivery slots, sending timely Chrome notifications when delivery windows open.

This open-source extension operates with a reasonable refresh rate to ensure account safety and offers an ethical approach to tracking delivery availability without causing unfair advantages. Easy to use, simply add items to your cart on supported services, navigate to the checkout shipping schedule page, and let the extension run in the background. Continuous updates and a detailed user tutorial are available to help maximize convenience and efficiency in securing delivery slots.

User reviews

After several days of trying to get a delivery slot, this finally got me one. I can now help my parents do the same and in this day and age, every trip outside is a risk for them. It seems strange to say this but if this app lets someone get a delivery rather than go out, it may well save a life.

It works within 10 minutes! Didn't know prime now delivery windows would open up at random times, not just at 12:00 am!
