About ShipBackBy

ShipBackBy is a free-to-use US holiday return deadline calculator. Pick a retailer, enter a purchase date (and delivery date when the policy counts from arrival), and get the last day to return — holiday window or standard count — with an optional ICS reminder.

Deadlines are computed in your browser from versioned public policy JSON shipped with the site. We cite source URLs and last-verified dates so you can see where a number came from.

Verified vs Unverified: Retailers and holiday windows marked Verified have been checked against the retailer's published help or returns page on the date shown. Unverified cells stay labeled Unverified. We do not invent holiday cutoffs, fees, or guarantee that any item will be accepted.

Not affiliated: We are not affiliated with Amazon, Walmart, Target, Best Buy, Costco, Apple, Home Depot, Nordstrom, Nordstrom Rack, Microsoft, Sephora, Macy's, or any other retailer. Trademark names belong to their respective owners.

Policies change: Always confirm deadlines and eligibility on the retailer's official help center or order page before you ship anything back.

Privacy: Your household list stays in browser localStorage. We do not require an account. If analytics or ads are enabled via environment variables, those third parties may collect standard web traffic data under their own policies. See the Privacy Policy.
