Amazon Quantity Double-Check

Requires you to confirm the quantities in your Amazon cart before proceeding to checkout.

Amazon Quantity Double-Check adds a confirmation step before you proceed from your Amazon cart to checkout. The extension attempts to read and display the quantities of items in your cart, giving you an opportunity to verify them before continuing. If Amazon's cart layout changes or the extension cannot reliably read the quantities, it will block checkout rather than allow you to proceed without a warning. You can then review the quantities yourself and explicitly confirm that you checked them before continuing. This extension is designed to help prevent accidentally purchasing multiple copies of an item when you intended to purchase only one. It does not place orders, change your cart quantities, or make purchases for you. It only adds a confirmation step between your Amazon cart and checkout.
