Prepare item numbers and quantities in advance for high-demand Costco, Walmart, and Sam's Club releases. Installation is free. List and cart actions require a one-time $5 USD lifetime license purchased from the developer through Stripe. Google is not the seller and does not process this payment. Chrome Web Store reviewers receive free test access. Shopping List Adder helps you prepare known product numbers before high-demand Costco, Walmart, and Sam’s Club releases go live. Build shopping lists in advance by pasting product numbers, selecting quantities, and saving the items before the release begins. When sales open, go directly to your prepared list, refresh normally, and use the retailer’s Add to Cart flow when it becomes available. This reduces repeated searching during a busy release and provides a shorter route to products you already know about. Features: - Batch-add product numbers to supported retailer shopping lists. - Set one default quantity for an entire batch. - Override quantities for individual items using itemNumber,qty. - Prepare known products before retailer availability opens. - Recover from short-lived login state without manually refreshing before every Add to List action. - Add supported shopping lists to the retailer’s cart where the normal retailer workflow allows it. - Restore a lifetime purchase using an opaque license code. - Redeem optional time-limited trials that bind to the first Chrome installation using them. Example: 1992235,2 1814970 18555463299,3 The example adds two units of the first item, the default quantity for the second item, and three units of the third item. Adding an item to a shopping list does not reserve inventory or place it in the checkout cart. Inventory, pricing, eligibility, purchase limits, retailer availability, and successful checkout are never guaranteed. Shopping List Adder is independent software and is not affiliated with, sponsored by, or endorsed by Costco, Walmart, or Sam’s Club. It does not bypass retailer waiting rooms, queues, security controls, account restrictions, purchase limits, or terms. Retailer credentials and item lists are not sent to the Shopping List Adder licensing server. The licensing service receives only a random installation identifier and an opaque paid, trial, or reviewer license code. Payments are completed on Stripe’s hosted checkout page. The extension never receives or stores complete card numbers. Support: support@phantomrestock.com Website: https://lists.phantomrestock.com Privacy policy: https://lists.phantomrestock.com/privacy
